Question

question 3.1

simplify the following expressions using the correct order of operations:

(15 - 10 \div 2 + 3 =)

((5 - 2) * 7 - 1 =)

(8 \div 2(2 + 2) =)

(300 \div (7 - 2)^2 * 2^2 =)

Explanation:

Simplify expression A

$$ 15 - 10 \div 2 + 3 = 15 - 5 + 3 = 10 + 3 = 13 $$

Simplify expression B

$$ (5 - 2) * 7 - 1 = 3 * 7 - 1 = 21 - 1 = 20 $$

Simplify expression C

$$ 8 \div 2(2 + 2) = 8 \div 2(4) = 4(4) = 16 $$

Simplify expression D

$$ 300 \div (7 - 2)^2 * 2^2 = 300 \div 5^2 * 4 = 300 \div 25 * 4 = 12 * 4 = 48 $$
