Answer 1

Step-by-step explanation:

Addition and Subtraction:

All numbers are converted to the same power of 10, and the digit terms are added or subtracted.

Example: (4.215 x 10-2) + (3.2 x 10-4) = (4.215 x 10-2) + (0.032 x 10-2) = 4.247 x 10-2

Example: (8.97 x 104) - (2.62 x 103) = (8.97 x 104) - (0.262 x 104) = 8.71 x 104
