Question

Calcula. a) 6 + [5 + (7 + 2)] = b) 8 + [4 – (3 + 5)] = c) 10 – [6 + (2 + 7)] = d) 15 – [2 – (6 – 10)] = e) 15 – [10 – (8 + 4)] = f) 12 – [7 – (2 – 10)] = g) (–6 ) + [5 + (2 – 12)] = h) (–7) – [3 – (4 – 9 pls nesecito ayuda

Answer 1

Explicación paso a paso:

a) 6 + [5 + (7 + 2)]

6+ 14 = 20

b) 8 + [4 – (3 + 5)]

8 - 4 = 4

c) 10 – [6 + (2 + 7)]

10 - 15 = -5

d) 15 – [2 – (6 – 10)]

15 - 6 = 9

e) 15 – [10 – (8 + 4)]

15 + 2 = 17

f) 12 – [7 – (2 – 10)]

12 - 15 = -3  

g) (–6 ) + [5 + (2 – 12)]

-6 -5 = -11

h) (–7) – [3 – (4 – 9)]

-7 -8 = -15
