9 - (-15) • 3 + 4 ÷ (-2)

Answer 1

52

Explanation:

9 - (-15) • 3 + 4 ÷ (-2)

9 - (-15) • 3 + 4 ÷ (-2)

9 + 15 • 3 + 4 ÷ (-2) = 9 + 15 • 3 + 4 ÷ -2

9 + 15 • 3 + 4 ÷ -2 = 9 + 45 + 4 ÷ -2

9 + 45 + 4 ÷ -2 = 9 + 45 + -2

9 + 45 + -2 = 9 + 45 + 2 (change the negative to positive)

9 + 45 - 2 = 54

54 - 2 = 52

Answer 2

9 - (-15) x 3 + 4 / (-2)

9 + 15 x 3 -2

9 + 45 -2

54 - 2
