Question

What should be done first to evaluate the expression? 9 - 4 ÷ 5 + 3 × 6 A: Add 5 and 3 B: Multiply by 3 and 6 C: Divide 4 by 5 D: Subtract 4 from 9

Answer 1

To evaluate the expression 9 - 4 ÷ 5 + 3 × 6, first divide 4 by 5.

Step-by-step explanation:

To evaluate the expression 9 - 4 ÷ 5 + 3 × 6, we need to follow the order of operations, which is also known as PEMDAS. This stands for parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right).

Step 1: First, we perform the division: 4 ÷ 5 = 0.8.

Step 2: Next, we perform the multiplication: 3 × 6 = 18.

Step 3: Now we can proceed with the subtraction and addition: 9 - 0.8 + 18 = 26.2.

Therefore, to evaluate the expression, we should first divide 4 by 5.
