Question 36

Adding and Subtracting with Significant Figures

Answer 36

When adding and subtracting measurements, round your answer so that it has the same precision as the least precise measurement Ingrid the equation.
Ex. 25.46 cm - 7.8 cm = 17.66. To precise : should be 17.7.

Question 37

Multiplying and Dividing with Significant Figures

Answer 37

When multiplying and dividing measurements, round the answer so that it has the same number of significant figures as the measurement with the fewest significant figures.
