Problem

Solve this problem, expressing the result with engineering notation.

(12 x 10-3) + (2.2 x 10-3) = _____

Procedure

1. Adjust to produce identical exponents,  if necessary

(12 x 10-3) + (2.2 x 10-3)

Adjustment is not necessary. Exponents are equal.

10-3

2. Add or subtract the coefficients, as designated

(12 x 10-3) + (2.2 x 10-3)

12 + 2.2 = 14.2

3. Attach the common power of ten

(12 x 10-3) + (2.2 x 10-3) = 14.4 x 10-3

The solution is already normalized

 
Solution

(12 x 10-3) + (2.2 x 10-3) = 14.4 x 10-3
