19+3 ( (8+3) -9÷3)
-
Evaluate the expression in the innermost parentheses:
19 + 3((8 + 3) - 9 ÷ 3) = 19 + 3(11 - 9 ÷ 3)
Evaluate the expression in the remaining parentheses. Division first:
19 + 3(11 - 9 ÷ 3) = 19 + 3(11 - 3)
Then subtraction:
19 + 3(11 - 3) = 19 + 3 × 8
Multiplication first:
19 + 3 × 8 = 19 + 24
Finally the addition:
19 + 24 = 43
19 + 3((8 + 3) - 9 ÷ 3) = 19 + 3(11 - 9 ÷ 3)
Evaluate the expression in the remaining parentheses. Division first:
19 + 3(11 - 9 ÷ 3) = 19 + 3(11 - 3)
Then subtraction:
19 + 3(11 - 3) = 19 + 3 × 8
Multiplication first:
19 + 3 × 8 = 19 + 24
Finally the addition:
19 + 24 = 43
