**Significant figures and decimal place**

**Rules of significant figures**

- Trailing zeros or the final zero in a whole number or a decimal place is considered a significant figure.

*e.g: 0.0**420**, 0.**4300**,**430**(numbers in red are significant figures)*- Zeros in some cases can be considered as
**not a significant figure.***e.g: express 34235 as 1 significant figure. The answer will be 30000. Reason behind why we round down is because anything below 5 round it down while any number 5 and above we would round up. (See more in the decimal place section.)*

**Rules of Decimal place**

- If a number is above 5 then we round up the number if the number is 4 an below we round down.

*e.g: express 110 to the nearest hundreds and since the 1 at the tens position is below 5 we round it down.*
