Alguien que me ayude porfavor​

Answer 1

Respuesta:

a. (-13) - 15 - 22 × 9 + (-11)

(-13) - 15 - 198 + (-11)

-13 - 15 - 198 - 11 = -237

b. -4 + [(-6+(-8))÷(5-(-2))]

-4 + [(-6-8) ÷ (5+2)]

-4 + [(-14) ÷ 7]

-4 + [(-2)]

-4 + [-2]

-4 -2 = -6

c. 17-[(4-(-12))÷(15+(-7))]×(-11)

17 - [(4+12) ÷ (15-7)] × (-11)

17 - [ 16 ÷ (-8)] × (-11)

17 - [(-2)] × (-11)

17 - [-2] × (-11)

17 + 2 × (-11)

17 - 22 = -5

d. -5+(9-8÷4+1)-215×5

-5 + (9-2+1) - 1075

-5 + 8 - 1075

-1080 + 8 = -1072

e. [(-10)×(-8)]-{[(-5)-7]÷[(-2)+6]}

[80] - {[(-12)] ÷ [4]}

[80] - {[(-3)]}

[80] - {[-3]}

[80] - {-3}

80 + 3 = 83

f. (-18)×(-8)-(-5)-27÷(-9)

144 -(-5) + 3

144 + 5 + 3 = 152
