Exercícios de Expressão Numérica

Calcule o valor das expressões numéricas:

1) 13 + ( 10 – 8 + (7 – 4)) = (R: 18)
2) (10 . 4 + 18 – ( 2 . 3 +6)) = (R:46)
3) 7 . ( 74 – ( 4 + 7 . 10)) = (R: 0)
4) ( 19 : ( 5 + 3 . 8 – 10)) = (R : 1)
5) 7 – ( 1 + 3)
6) 9 – ( 5 – 1 + 2)
7) 10 – ( 2 + 5 ) + 4
8) ( 13 – 7 ) + 8 – 1
9) 15 – ( 3 + 2) – 6
10) ( 10 – 4 ) – ( 9 -8) + 3
11) 50 – [ 37 – ( 15 – 8 ) ]
12) 28 + [50 – (24 – 2) -10 ]
13) 20 + [ 13 + (10 – 6) + 4]
14) 52 – { 12 + [ 15 – ( 8 – 4)]}
15) 25 + { 12 + [ 2 – ( 8 – 6 ) + 2 ]} =
16) { [ ( 18 – 3 ) + ( 7 + 5) – 2 ] + 5 } – 12 = (R:18)
17) 65 – { 30 – [ 20 – ( 10 – 1 + 6) + 1 ]} = (R: 41)
18) 45 + { 15 – [ ( 10 – 8 ) + ( 7 – 4) – 3 ] – 4 } = (R:54)
19) 40 + { 50 – [35 – ( 25 +5) – 1 ]} + 7 = (R:93)
20) 38 – { 20 – [ 22 – ( 5 + 3) + ( 7 – 4 +1)]} = ( R:36)
21) 26 + { 12 – [ ( 30 – 18) + ( 4 – 1) – 6 ] – 1 } = (R::28)
22) 25-[10 + (7 - 4)] = (R:12)
23) 32+ [10-(9-4)+8] = (R:45)
24) 45-[12-4+(2+1)] = (R:31)
25) 70-{20-[10-(5-1)]} = (R:56)
26) 28 + {13 - [6 -(4 + 1) + 2] - 1 } = (R:37)
27) 53-{20-[30-(15-1+6) + 2 ]} = (R:45)
