Quick reminders
- Start counting significant figures from the first non-zero digit.
- Look at the next digit to decide whether to round up or keep it the same.
- Digits after the required significant figures become zeros if needed.
- For decimals smaller than 1, zeros before the first non-zero digit are not significant.
