Question

resolva as expressões :
2+4-2=

2{3+1 [ 5-4(3.2)[-8{=

-2 +6-10-4=

261-(45+54)=

(57-24)+(43-34)=

7x(12+8)=

45:3+15:10

1+6x10:5

Answer 1

Resposta:

2+4-2 = 6 - 2 = 4

2{3+1 [ 5-4(3.2)] -8} = 2 {4 [ 1 +6 ] -8} = 2{ 4 + 7 - 8 } = 2{ 11-8} = 2 + 3 = 5

-2 +6-10-4 = 4 - 6 = -2

261-(45+54)= 261 - 99 = 162

(57-24)+(43-34) = -7 +9 = 2

7x(12+8) = 7× 20 = 149

45:3+15:10 = 15 + 1,5 = 16,5

1+6x10:5 = 1+ 60: 5 = 1+ 12 = 13

espero ter ajudado!!
