e. ( –10 – 2 x 4 ) ÷ ( – 2 – 1 ) + ( – 6 ) ÷ ( – 3 ) – ( – 1 )=

Answer 1

Respuesta:

SE RESUELVE POR EL SIGUIENTE ORDEN: PARÉNTESIS, EXPONENTES, MULTIPLICACIÓN Y DIVISIÓN, Y AL ÚLTIMO LAS SUMAS Y RESTAS.

a. 5 x (– 2) – (– 8 + 2) +(– 8) = -12

= -10 +8 -2 -8

= -12

c. ( – 2 – 3 + 4 ) x 5 – 9 x (– 2 – 6) = 67

= (-1)x5 -9(-8)

= -5 +72

= +67

b. (+ 5) x (–12) ÷  (+ 4) = -15

= -60 ÷ 4

= -15

d.(– 5 – 10 – 32) x (4 – 8 – 16) = 940

= (-47)x(-20)

= +940

e. ( –10 – 2 x 4 ) ÷ ( – 2 – 1 ) + ( - 6 ) ÷ ( – 3 ) – ( – 1 )= 7

= (-10 -8) ÷ (-3) + 2 +1

= (-18) ÷ (-3) + 1

= 6 + 1

= 7
