## What is the number greater than 0?

All whole numbers greater than 0 are also called the positive integers. the positive integers start with the number one and go all the way to infinity. On a number line the positive integers all lie to the right of 0.

## What is a right end zero?

Zeros that appear after all nonzero digits are called right-end zeros. Right-end zeros in a number that lacks a decimal point are not significant. Right-end zeros in a number with a decimal point are significant. This is true whether the zeros occur before or after the decimal point.

## What does an insignificant zero do?

An insignificant zero functions as a placeholder for the decimal point. For a number with left-end zeros, such as 0.000416, it can be written as 4.16 × 10−4 with 3 significant figures. In some cases, scientific notation is the only way to correctly indicate the correct number of significant figures.

## Why are trailing zeros not significant?

The trailing zeros do not count as significant. Trailing zeros in a number containing a decimal point are significant. For example, if a measurement that is precise to four decimal places (0.0001) is given as 12.23, then the measurement might be understood as having only two decimal places of precision available.
