1. Completa las siguientes tablas:

1er tabla

a | b | a × b | a ÷ b

-8 | -2 | - 16 | - 4

-4 | -1 | + 4 | + 4

+10 | - 5 | - 50 | - 2

+18 | -9 | - 162 | - 2

-3 | +3 | -9 | - 1

2da tabla

a | b | a × b | a ÷ b

+32 | -8 | - 256 | - 4

- 4 -44 | +11 | - 484 | - 4

4 +64 | - 4 | - 256 | - 16

-36 | -9 | +324 | +4

+11 | -11 | -121 | - 1

2. Resuelve las siguientes operaciones combinadas:

a) - 3 (4 - 2 + 5) =

a) - 3 (4 - 2 + 5) = -3 (7)

a) - 3 (4 - 2 + 5) = -3 (7) Rta ----> - 21

b) -5 × 3 + 8 - (4 - 1 × 5) =

-15 + 8 - (4 - 5) =

-15 + 8 - (-1) =

-15 + 8 + 1=

Rta ----> -15

c) -15 (-4) + 2 [-3 (2) + (6 - 2 (8))] =

60 + 2 [ -6 + (6 - 16)] =

60 + 2 [ -6 + 6 - 16] =

60 + 2 [-16] =

60 - 32 =

Rta ----> 28

d) -12 × [ -6 - 10 ×(-2 -3)] =

-12 × [ -6 -10 × (-5)] =

-12 × [-6 + 50] =

-12 × 44 =

Rta ----> -528
