Question

3. When adding or dividing measured numbers, we don't count significant figures. Instead, we look at the precision of the measured numbers. The answer can only be as precise as the least precise measurement.
For example: 10.1 +93.4 = 103.5, because both 10.1 and 93.4 are precise to the tenths place. Solve the following problems assuming all the numbers are measured. Report the correct number of
significant figures.
a. 87.3 +0.001 =
b. 0.201 +0.92 =
c. 320 +8.41 =
d. 1200-60=
