Question

2. Evaluate.
a. [(-17) + 17 + (-2)]
b. (-1) (-1) X (-1) (-1) (-1) X (-1) x (-1)
C. [(-60) = 6] + [ 35 + 7)
d. (-3) * (-6) * (-2) * (-1)
e. [(-42) + (-7)] * [ 24 + (-3)]​

Answer 1

Step-by-step explanation:

(a) ((-17)+17+(-2))

first we will add the same sign integers

=(-19)

then we will subtract because the different sign integers are subtracted.

= (-19+17)

=(-2)

(b)(-1)(-1)×(-1)(-1)(-1)×(-1)×(-1)

1×1×(-1)×1

1×(-1)

(-1)

Answer 2

Answer:

a.[(-17) +17+(-2)]

[-17 + 17 - 2]

[ 0 -2] = -2

b.(- 1)(-1)×(-1)(-1)(-1)× (-1)(-1)

1×-1×1

1 × -1 = -1

c.[(-60)- 6)] + [ 35 + 7 ]

-66 + 42

= - 24

d.(-3)×(-6)×(-2)×(-1)

18 × 2 = 36

e.[(-42)+(-7)] × [ 24 (-3)]

49×(-72) = - 3578
