Small numbers are often very tricky to handle. While dealing with such small numbers, you have to be very careful to maintain the accuracy of your readings.

Rounding off a number is important in our daily lives to relieve ourselves from anxiety when dealing with peculiar details. We feel convenient in whole numbers, but a single zero can cause serious changes in lab-scale measurements.

Significant figures in this number are four.

Because "the leading zeros are insignificant."

After rounding off the number, you get ** 5273, **as there isn't any digit in the fifth place.

There are five decimals in this number.

Significant figures in this number are 3. And these numbers are 1,5,0.

"The reason why only these numbers are significant is that zeros on the left side are not significant."

The total number of decimals in this number is five.

Writing it in Scientific Notation, you will get 1.5 × 10^{-3}

Significant figures exhibit the quantities. Moreover, the more elaborative the quantity is, the more correct your readings are.

The answer is 2

**Rule:**

"The zeros coming at the right side of a number are not significant."

There are several rules to calculate significant figures of a given reading. Fredrich Gauss determined these rules to eradicate round-off error. Before that, people were rounding off the numbers without considering that the quantity's value changes after rounding off.

Decimals present: 4

These are written as 0.__0025__

Written in words: zero point zero, zero two five.

Scientific Notation: 2.5 × 10^{-3}

Significant figures are easy to give precise measurements; if you get a very small reading, you can round off to your specified significant figures for calculations. Moreover, they also provide the degree of error in your readings.

Significant figures in 900 are **1**.

Note:

According to significant figures rules, zeros coming at the left end of a number are not significant.

Decimals: 0

Scientific Notation: 9 × 10^{2}

Engineers often feel hard to deal with long numerical values of quantities. In a numerical problem, chances of errors occur due to the presence of decimal points and repeated zeros. However, denoting significant figures minimizes these errors as the number of significant figures determines the precision.

The number of Sig Figs in 6000 is **1. **That is ** 6**000.

There isn't any decimal in this number.

In words: "Six Thousand."

Answer: **5734. **

Significant digits in this number: 6

According to significant figures rules, a non-zero whole number is significant because all the digits are non-zero.

There are no decimals in it.

Scientific-Notation: 5.73385 × 10^{5}

There are (**3**) significant figures in 2020.

These three significant figures are 2,0,2. However, these are only significant figures because the trailing zeros are insignificant according to rules, and the zeros between non-zero digits are considered significant.

Scientific notation is used to express a large quantity easily. However, people cannot with the bulk of decimals. Therefore, a system was developed to express numbers in the powers of 10.

0.0027 can be converted in scientific notation as = **2.7 ****× 10 ^{-3}**

Significant figures in this number are = **2**

There is only **one **significant figure in 0.01.

Rule: A zero leading a number is not non-significant.

A significant figure is the simplest method to determine the precision of a calculation. If a number contains more significant figures, then it is more accurate.

Decimals present in it: 2

Scientific notation: 1 × 10^{-2}

The number of sig figs in this number is **3**

Denoted as: 0.00__580__

Rule: Trailing zero in decimal is considered significant. Therefore, the number has three significant figures.

You can estimate the uncertainty in any maths result by checking out its significant figures,

Significant figures in 1000 are **1**.

**Rule**: The answer is (1) because the zeros on the left side of a whole number are insignificant.

Fredrich Gauss developed this system of how to round-off numbers. For example, if different people weigh a small quantity in grams, they will get different values in decimals. Significant digits give us a standard to determine the precision of a number and round them to get consistent results.

Significant figures in 1261.63 are 6.

Rule: All non-zero digits are significant.

According to sig fig rules, the non-zeros and zeros on the left side of a decimal point are significant.

Decimals: 5

Scientific notation: 6.9 × 10^{-2}

Zeroes are often taken for granted and ignored when it comes to daily life routines. You don't talk in significant figures; you don't say I have 1.00 dollars in my pocket. However, in scientific calculations, we focus on every minute detail to avoid errors. For this purpose, we use significant figures.

There are **three **significant figures in 0.00208.

Decimals: 5, (0.** 00208**)

We round off numbers because they give us ease in speaking and narrating. Thus, for example, you don't tell that your country's population is 22.058960 million; instead, you say that your country's population is almost 22 million. You do this because it's convenient to give a generic number.

Answer: Your number will become 42691 because the sixth number, 2, is less than 5.

No. of significant figures: 6 because all numbers are non-zero.

In this query, we will round off 0.85473 to 4 significant figures.

Sig figs are the digits that are necessary to indicate a number with correctness.

Answer: **8547 **

We got this answer by applying the sig fig rule, stating, "0 at the start of a number are not significant."

And 3 < 5.

No. of decimals in the number: 5

The number 0.0010 is a decimal number, and while finding the significant figures, you should the rules about it.

- Rule: "Zeros before a number are rendered insignificant."
- Rule: "Zeros coming after a decimal number are significant."

Answer: the number of significant figures in 0.0010 is **2**.

Significant figures in 0.1 are 1.

Rule: "Zero on the extreme left side of a number is insignificant."

In terms of scientific notation, the number is represented as 1 × 10^{-1}.

Decimals: 1

Significant figures: 6

By rounding off the number up to four significant digits, the answer will be **5734**.

Number of decimals in this number: 0

Scientific-Notation: 5.73385 × 10^{5}.

The original number has significant figures = 4.

After rounding off to 2 sig figs, the number becomes = 76 or 7600

Reason: "The third digit is 4 < 5, so we will not add 1 to the digit at 2^{nd} place."

Total significant figures in this number are 4.

Rule: "Significant figures rule implies that if the number contains all non-zero digits, then all digits are significant, as in the case of 437.6"

Round off the number to 2 significant figures = 44 or 440

Decimals: 1 (437.** 6**)

If you are a maths student, you have to learn how to deal with numbers and round them off correctly.

Round off 4382 to 1 sig fig we get = 4 or 4000

The reason why we get this answer = 3 < 5.

We can write this number in scientific notation = 4 × 10^{3}.

While solving maths calculations, you may come up with an answer containing a long string of decimals. Such a number is difficult to handle.

So, scientists and mathematicians developed this method of representing a number in terms of powers of 10. This method is called scientific notation.

56000 = 5.6 × 10^{4}.

Significant figures in 0.0050 are 2.

That's according to rules because "zeros at the end of a decimal number are significant."

Decimals: 4

Scientific Notation: 5.0 × 10^{-3}.

In words: zero point zero, zero five zero.

You may not notice, but you often use significant figures when you are representing any number. An average human mind is not good at remembering many numbers; It is also handy to get a rounded-off number.

For example, when you say there are 30,000 people in the concert, the number of people approaches 30,000; however, they may be more or less than that number.

While handling such numbers with decimals, you should know that the 0's at the start of a number are excluded from significant digits.

Significant figures in this number are** 2**.

Decimals: 4

Scientific notation: 9.9 × 10^{-3}.

E-notation: 9.9e^{-3}

We conventionally use whole numbers in our routine life. For example, suppose you have to buy groceries from a shop.

You can't buy things at a small price of 0.0200 because our transactions are based on whole numbers. However, in maths, every 0 is important, and a scientist cannot afford even a slight change in the readings.

Answer: Significant figures in 0.0** 200 **are 3

"Based on rules, we know that zeros at the start of a number are insignificant."

Decimals: 4 (0** .0200**)

The 0.48 contains significant figures = 2, that are 0.__48__

Number of decimals = 2

After rounding off, the number becomes, **0.5**

A significant figure in 1000 is only **1.**

Why is it so?

Because in whole numbers, all zeros at the end are dropped. However, it is not the same if the number is 1.000 now the number of sig figs is different.

Significant figures in this number are 6.

There are six significant digits because the zeros trapped by non-zero numbers are significant, and the trailing zeros after a decimal point are significant.

The two zeros after the point indicate uncertainty, and the real answer may exceed or decrease.

A significant figure in 20 is** 1**.

Significant digits are about the uncertainty in the measurements and help you define your standard of measurements.

Note that 20 is way different from 20.00 in terms of significant figures.

200 has significant figures = 1

Now the question arises why is it so?

The answer is, "The number of 0's present at last in a number without a decimal is ignored."

Scientific Notation: 2 × 10^{+2}.

Significant figures in 200.0 are 4.

You cannot write 200.0 as 200 because zero after a point indicates a certain uncertainty level is present inside the decimal point.

Answer: Significant figures in 4000 are 1.

It is represented as ** 4**000.

The rule states that "0's trailing a whole number are insignificant".

Significant figures are an easy way to represent precision in a number. Hence, they are extensively used in maths.

They are four in 500.0

They are four because we consider zeros after a decimal point and between non-zeros as significant.

Scientific Notation: 5.000 × 10^{2}.

In Words: Five hundred point zero.

Significant figures in 1.00 are 3.

Decimals: 2 and indicates as, 1.__00__

It is often tricky to deal with 0's because there are different rules behind them.

- If a zero is coming after a decimal point, then it is rendered as significant.

Sig fig in this number is only 1.

Rule: "zeros before a non-zero in a number are ignored."

Significant figures do not give exact value; they are good enough to give you an answer that you can manipulate.

For example, a number 8.996456684 is not easy to deal with; however, a number rounded-off to significant figures can give you a reasonable answer like 9.

Scientific notation: 2 × 10^{-3}.

Decimals: 3 (0.** 002**).

There are two sig figs in 7.0

Decimals: There is only one decimal in this number that is, 7.__0__

Scientific Notation: 7.0 × 10^{0}

Words: Seven point zero.

Significant figures are very important in calculations and measurements as they give how precise measurements are.

Significant figures in 2.0800 are 5, described as __2.0800.__

Decimals: 4

These decimals are 2.__0800__

Significant figures in 0.00630400 are **6**.

"Leading zeros are insignificant in both whole numbers and decimals. However, zeros trapping inside other numbers and zeros coming after a decimal point are deemed significant."

State the significant digits in 1000.0.

Significant figures are **5**.

Why?

"Because such numbers having zeros between a non-zero number and a decimal point are significant."

Decimals: 1

Scientific Notation: 1.0 × 10^{+3}

E-Notation: 1.0e^{+4}

Words: one thousand point zero.

The answer is ** 1**.

Decimals: no decimal numbers.

People are confused with sig figs. For example, sometimes, students confuse the number of significant figures between 100 and 100.0.

If you are the one who is having sleepless nights due to this misperception, you have to understand these simple rules.

After rounding off, we get **0.984**

0.98350 is a decimal number, and it is probably hard to inquire because zeros can cause a problem in significant figures. So you have to know the rules first to get a full grasp.

Significant figures in 0.98350 are (5) and shown as 0.__98350__

This number is a big one; however, physicists perform volumes of equations to get results.

For just an example: The value of pie is a recurring decimal.

Here significant figures come into play to round off your value to the least unprecise results. After rounding off, the value becomes 3.14.

By rounding off 14.587020, we get 14.59, (7 > 5).
