## How to do significant figures

### How do you solve 3 significant figures?

We round a number to three **significant figures** in the same way that we would round to three decimal places. We count from the first non-zero **digit** for three **digits**. We then round the last **digit**. We fill in any remaining places to the right of the decimal point with zeros.
