Question

Determina el valor de M=A+B

Answer 1

$A = (( - 7 + 5 - 2)( - 2) + 4) \div ( + 6) - ( - 10 + 3) \div ( + 7) \\ A = (( - 4)( - 2) + 4) \div ( + 6) - ( - 7) \div ( + 7) \\ A = ( 8 + 4) \div ( + 6) + 1 \\ A = ( + 12) \div ( + 6) + 1 \\ A = 2 +1 \\ A = 3$

$B = 1 - ( - 4 \times ( - 2 \times ( - 8 + 5 \times 2) - 3 - 4 \times 2) - 5 + 6 \times 3) \\ B = 1 - ( - 4 \times ( - 2 \times ( - 8 + 10) - 3 - 8) - 5 + 18) \\ B = 1 - ( - 4 \times ( - 2 \times 2 - 11) + 13) \\ B = 1 - ( - 4 \times ( - 4 - 11) + 13) \\ B = 1 - ( - 4 \times - 15 + 13) \\ B = 1 - (60 + 13) \\ B = 1 - 73 \\ B = - 72$

$M=A+B \\ M=3+( - 72) \\ M = 3 - 72 \\ M = - 69$
