ayuda plis es para hoy doy coronita

Answer 1

Resultados:

1)

$(- 1)( - 2) ( + 4) = \\ 1 \times 2 \times 4 \\ = 8$

2.

$- ( - 1)(3)( + 2) = \\ 1 \times 3 \times 2 \\ = 6$

3.

$( + 3)( - 1)( - 1)( + 1)( - 1)( - 1) = \\ 3 \times 1 \times 1 \times 1 \times 1 \\ = 3$

4)

$- ( + 2)( - 1)(2)( - 1)( - 1) = \\ 2 \times 1 \times 2 \times 1 \times 1 \\ = 4$

5.

$( - 12) \div ( - 2) = \\ 12 \div 2 \\ = 6$

6.

$( - 14) \div ( - 2) = \\ 14 \div 2 \\ = 7$

7.

$- ( - 18) \div ( - 3) = \\ 18 \div ( -3 ) \\ = - 6$

8.

$- ( + 32) \div ( + 2) = \\ - (32 \div 2) \\ = - 16$

9.

$( + 22) \div ( + 2) = \\ 22 \div 2 \\ = 11$

10. (lo dejo resuelto abajo)

11.

$- ( + 30) \div ( - 2) = \\ 30 \div 2 \\ = 15$

12.

$( - 50) \div ( + 2) \\ - (50 \div 2) \\ = - 25$

13.

$( + 40) \div ( - 4) \\ - (40 \div 4) \\ = - 10$

14.

$( + 10) \div ( - 5) = \\ - (10 \div 5) \\ = - 2$

15.

-(-40)÷(-8)=

40÷(-8)

= -5

16.

(-32-23)÷(2+3)=

-55÷5

= -11

17.

(-5-1)÷3+3=

-6÷6

= -1

18.

(-32+10)÷(12-14)=

-22÷(-2)

= 11

19.

(+14+10)÷(2-6)=

24÷(-4)

= -6

20.

+(2+4)(2-4)=

6 × (-2)

= -12

21.

-(12-4)(-2+4)=

-16 × 2

= -32

22.

-(2+1)(2-4)=

-3 × (-2)

= 6

10.

(+12)÷(+4)=

12÷4

=3
