Question

Si A = 7 + (-49) + (+15) + (+18) + (-19) +(-25) + (+48) + (+2) y B = -32 + (-19 + 14) + (-7) + (+6) + (+1) hallar el valor de. (A + B + 20)

Answer 1

A = 7 -49 +15 +18 -19 -25 +48 +2

B = -32 -19 + 14 -7 +6 +1

hallar el valor de: (A + B + 20)

A = -3

B = -37

A + B + 20 = -40 + 20 = -20
