$[23-(10+5×2)]+9÷3-1$
​

Answer 1

Respuesta:

a)  6 + [ 5 + (7+2)] = 6 + 5 + 8 = 19

 

b) 8 + [4 - (3+5)] = 8 + 4 -8 = 4

 

c) 10 - [6 + (2+7)] = 10 -[15] = 10 -15 = -5

 

d) 15 - [2 - (6-10)] = 15 - [2 + 4] = 15 - 6 = 9

 

e) 15 - [10 - (8+4)] = 15 - [10 -12] = 15 + 2 = 17

 

f) 12 - [7 - (2-10 )] = 12 - [7 + 8] = 12 - 15 = -3  

 

g) (-6) + [5 + (2-12)] = -6 + 5 -10 = -11  

 

 

h) (-7) - [3 - (4-9)] = -7 -[3 +5] = -7 - 8 = -15  

 

i) (2-10) + [5 - (8 +2)] = -8 + 5 -10 = -13  

 

j) (12-3) - [1 - (2-6)] = 9 - [1 +4] = 9 -5 = 4  

 

k) [9 -5] + [7-10] = 4 -3 = 1

 

l) [10 +2] - [5 -12] = 12 -[-7] = 12 +7 = 19  

 

m) [8 - 10] - (-2) = -2 +2 = 0
