Question

you should do what before you count the significant figures from the numbers in the problem? stack the numbers math first round rewatch

Explanation:

To determine significant figures in a calculation - related context (like addition, subtraction, multiplication, division of numbers), we first perform the mathematical operations (math first) on the numbers. Stacking numbers is not a standard step before counting significant figures, and rounding is done after determining the number of significant figures based on the operation result, not before. So the correct step before counting significant figures from numbers in a problem (when there's a calculation involved) is to do the math first.

Answer:

B. math first
