Consideraciones generales

Convención de signos

( - ) ( - ) = ( + )

( - ) ( + ) = ( - )

( + ) ( + ) = ( + )

( - ) / ( - ) = ( + )

( - ) / ( + ) = ( - )

Ejercicio 1

[(-5) + (-3) + 6] x [7 + 8 + (-10)] x [3 + (-2) + 4]

[ - 8 + 6 ] x [ 15 - 10] x [7 - 2]

[ - 2 ] x [ 5 ] x [ 5 ]

[ - 10 ] x [ 5 ]

- 50

Ejercicio 2

[2 x (-3) x 4] + [ (-5) x (-2)] + [6  x (-3) x (-2)]

[-6 x 4] + [10] + [(-18) x (-2)]

[-24 + 10] + [ 36 ]

[-14 + 36 ]

22

Ejercicio 3

[ 5 x 10 x (-3)] / [15 x (-1)]

[50 x (-3)] / [-15]

[-150] / [-15]

10

Ejercicio 4

[ (-3) + 4 + (-5) +6 + 2] - [7 + (-8) + (-10) + 4 +5]

[ 1 - 5 + 8] - [7 - 8 - 10 + 9)

[ - 4 + 8 ] - [- 1 - 1 ]

[ 4 ] - [ - 2]

4 + 2

Ejercicio 5

[3 x (-4)] + [5 x 2 ] + [10 x 3] + [(-8) x 5]

[- 12] + [10] + [30] + [-40]

[-2 ] + [- 10]

-12

Ejercicio 6

$\frac{4}{3} +\frac{1}{6} \\\frac{8+1}{6} \\\frac{9}{6}\\\frac{3}{2}$

Ejercicio 7

$\frac{4}{3}-\frac{1}{6} \\\frac{8-1}{6} \\\frac{7}{6}$

Ejercicio 8

$\frac{4}{5} x\frac{5}{3} x\frac{(-1)}{5} x\frac{5}{2} \\\frac{20}{15} x\frac{-5}{10} \\\frac{-100}{150} \\-\frac{2}{3}$

Ejercicio 9

$\frac{7}{2} /\frac{5}{2} \\\frac{14}{10} \\\frac{7}{5}$

Ejercicio 10

$\frac{3}{5} +\frac{8}{5} +\frac{7}{5} +\frac{-10}{5} \\\frac{11}{5} + \frac{-3}{5} \\\frac{8}{5}$
