{90-[83-5.(22-9)]}:16

Answer 1

Resposta:

12+{5-[14+(8+3)+1]

12+{5-[14+11+1]

12+{5-26]

[(3.7+9)+(7+9:3)]-(6+2).5

[(21+9)+(7+3)]-(6+2).5

[30+10]-8.5

40-40 =

0

[(18+3.2)+8+5.3]:6

[(18+6)+8+5.3]:6

[24+8+5.3]:6

[24+8+15]:6

47:6=

7,8

{90-[83-5.(22-9)]}:16

{90-[83-5.13]}:16

{90-[83-65]}:16

{90-18}:16
