Significant Figures

[Helpme19]

Hi, I do not know the rules on finding the significant figures in combined operation specifically addition and subtraction. Someone let me know and help me. Example is 102.45 + 5.0 - 0.022

Significant figures are not used with addition and subtraction; rather, you can use the number of decimal places.

If you don't know the rules, and are not taking a course where they are taught, then look them up! For example: https://www.purplemath.com/modules/rounding3.htm
