Question

What is the first step in evaluating the expression shown below? (12.9 – 3.1) × 6.2 – 2 + 43 A. Multiply 3.1 and 6.2. B. Add 2 and 43. C. Subtract 3.1 from 12.9. D. Subtract 2 from 6.2.

Answer 1

Answer: Subtract 3.1 from 12.9

Step-by-step explanation:

The first step in evaluating the expression (12.9 – 3.1) × 6.2 – 2 + 43 is to open the bracket first and then subtract 3.1 from 12.9 which will give 9.8.

This follows the rule of BODMAS which says that B which stands for Bracket must be opened and solved first in a given expression.
