Answer 1

Answer:

(a) -6

(b) -2

(c) 5

(d) 7

(e) 45

(f) 15

Step-by-step explanation:

(a) (-4) + 3 + (-5)

= (-9) + 3

= -6

(b) 5 + (-2) + (-5)

= 5 + (-7)

= -2

(c) 16 + (-4) + (-7)

= 16 + (-11)

= 5

(d) 4 + 15 + (-12)

= 19 - 12

= 7

(e) (-25) + 50 + 20

= (-25) + 70

= 45

(f) 40 + (-5) + (-20)

= 40 + (-25)

= 40 - 25

= 15
