Answer 1

Respuesta:

1) (3 - 8) + (5 - (-2)]

= (-5) + (5 - (-2)

= (-5) + (5 + 2)

= (-5) + 7

= 2

2) 17 - 2 + 4 - (2 - 5)

= 17 - 2 + 4 - (-3)

= 15 + 4 - (-3)

= 19 - (-3)

= 19 + 3

= 22

3) 5 - 6 - 2 - 11 - 8) - 3 + 6] + 5

= -1 - 2 - 11 - 8) - 3 + 6] + 5

=  -3 - 11 - 8) - 3 + 6] + 5

= -14 - 8) - 3 + 6] + 5

= -22 - 3 + 6 + 5

= -25 + 6 + 5

= -19 + 5

= -14

4) 1 - 15 - 3 + 2) - 15 - 16 - 3+ 4) - 2)

= -14 - 3 + 2) - 15 - 16 - 3+ 4) - 2)

= -17 + 2) - 15 - 16 - 3+ 4) - 2)

= -15 - 15 - 16 - 3 + 4) - 2)

= -30 - 16 - 3 + 4 - 2

= -46 - 3 + 4 - 2

= -49 + 4 - 2

= -45 - 2

= -47

5) 9:16:(-2)

= 0,5625:(-2)

= -0,28125

6) 2 [( -12 - 36): 6 + 10 - 5) : (-3)) - 6

= 2 [( -48): 6 + 10 - 5) : (-3)) - 6

= 2 [-8 + 10 - 5) : (-3)) - 6

= 2 [2 - 5) : (-3)) - 6

= 2 [-3) : (-3)) - 6

= 2 [1] - 6

= 2 - 6

= -4

7) 4-3-2-5-3--2-3.3)- 10:2+3)

= 1-2-5-3--2-3.3)- 10:2+3)

= -1-5-3--2-3.3)- 10:2+3)

= -9--2-3.3) - 10:2+3)

= -9 + 2 - 3 * 3) - 10:2 + 3

= -9 + 2 - 9) - 10:2 + 3

= -7 + 2 - 10:2 + 3

= 5 - 10:5 + 3

= 5 - 2 + 3

= 3 + 3

= 6

8) 14 - 1117 - 14 - 41 + 3} - 5

= -1.103 - 14 - 41 + 3} - 5

= -1.117 - 41 + 3} - 5

= -1.158 + 3 - 5

= -1.155 - 5

= -1.160

9) 4-12- 3- 5)-15-2).(-7-4:2)]

= -8 - 3- 5)-15-2).(-7-4:2)]

= -11 - 5)-15-2).(-7-4:2)]

= -16)-15-2).(-7-4:2)]

= -31-2).(-7-4:2)]

= -33.(-7-4:2)]

= -33. -11:2

= -33. -5,5

= 181,5

10) 10:[(3-5)-(2-4): 10:(-3-2)]

= 10:[(-2)-(2-4): 10:(-3-2)]

= 10:[(-2)-(-2): 10:(-3-2)]

= 10:[(-2) + 2): 10:(-3-2)]

= 10:[0 : 10:(-3-2)]

= 10:[0 : 10:(-5)]

= 10:[0 : (-5)]

= 10 : 0

= 0

11) (7-5)-13-2-4-2-3-10-2-8:4)

= (2)-13-2-4-2-3-10-2-8:4)

= -11-2-4-2-3-10-2-8:4)

= -13-4-2-3-10-2-8:4)

= -17-2-3-10-2-8:4)

= -19 - 3 - 10 - 2 - 8:4

= -19 - 3 - 10 - 2 - 2

= -22 - 10 - 2 - 2

= -32 - 2 - 2

= -34 - 2

= -36

12) 8:13-5-2 [-3.1-4)-6:(1-3)​

= 8:13-5-2 [-3-4)-6:(1-3)​

= 8:13-5-2 [-3-4)-6:(-2)​

= 8:13-5-2 [-7)-6:(-2)​

= 8:6 [-7)-6:(-2)​

= 1,3 {-13}: -2

= -17,3 : -2

= 8,6
