Question

a) 3.(-4)+25:5-7 =

b) 2.(-6+2)-18:(-6)+10=

c) -20:4.3+(12-8).(-2)=

d) (10:5-8).4+14:(8-7)=

Answer 1

Respuesta:

a).

$3 \times ( - 4) + 25 \div 5 - 7 \\ - 12 + 5 - 7 = - 14$

b).

$2 \times ( - 6 + 2) - 18 \div ( - 6) + 10 \\ 2 \times ( - 4) + 3 + 10 \\ - 8 + 3 + 10 = 5$

c).

$- 20 \div 4 \times 3 + ( 12 - 8) \times ( - 2) \\ - 15 + 4 \times ( - 2) \\ - 15 - 8 = - 23$

d).

$(10 \div 5 - 8) \times 4 + 14 \div (8 - 7) \\ (2 - 8) \times 4 + 2 \div 1 \\ - 6 \times 4 + 14 \\ - 24 + 14 = - 10$

Espero que te sirva :)
