Calcule o valor das expressões numéricas:
5 x 4 =2 =
16 : 2 + 5 =
6 + 3 x 5=
3 – 4 : 2 =
4 + 3 x 2 =
8 : 2 + 1=
3 - 6 : 3 =
7 x 3 + 5 =
5 + 3 x 2 + 4 =
1 x 3 + 4 x 5 =
6 x 3 – b 2 x 5 =
Calcule as expressões:
( 8 – 3 x 2) +1 =
( 5 + 2) x 3 + 5 =
7 x 3 + ( 4 + 3) =
( 8 - 2) x 4 + 4 =
( 10 + 2) x 3 + 2 =
( 5 + 3 x 5 - 2) x 5 + 1 =
( 7 + 5 x 2 + 4) + ( 4 x 2 )=
( 3 + 2) X ( 3 - 1)=
[ ( 8 : 2)+ ( 3 : 3)] – 1 =
[3 + 2 x 5 + ( 3 x 1)] – 2 =
8 x 3 + [ 10 + ( 3 – 1 x 2)] =
12 + [ 6 + ( 2 x 4 ) + 1 ] =
[ 5 + (4 x 3)]=
{ 4 + [ 3 x ( 2 - 1)]} : { 7 x 1 } =
[ (10 : 2) x 3 + 4] – 1 =
[ 7 + ( 4 x3) : 6] – 4 =
4 + ( 3 x 2) : 2 + 5 =
Calcule as expressões numéricas:
5 + { 3 + [( 7 x 3) + 1 ]} : {4 : 2 – 1} =
{( 16 : 2 ) x 2] – [( 18 : 3) x 2 ] =
9 – { 2 + [( 4 x 2) : 8 + 1] + 3} =
{[13 + (21 : 3)] : 5 + 2} – 2 =
2 – [(5 x 3) : 5 – ( 20 : 10)] =
{ 8 – [4 – (3 x 2) : 3]} + 5 =
{5 + [(3 x 2 - 1) + 4 x 2]} – [7 x 2 – 5] =
13 + {8 + [(24 : 3) : 4] + 3} + 2 =
{[(10 + 4) : 2 – 1]} : {3 x 2} =
8 – {4 x [(2 + 1) – 2]} =
{8 + [3 x (2 + 4) + 5 x (3 - 3)]} =
{10 + [(3 x 4) – 1] + [(7 x 1) x 2]} =
Arme e efetue as operações:
43 + 2647 + 5448 =
81 + 943 + 3851 + 976524 =
263871 + 654 + 8 + 16 =

230 + 1885 + 77 + 1106 + 84 =
15 + 4437 + 12095 + 1 + 9784 =
2635 + 33 + 8921 + 34 + 190 =
2150 – 146 =
623845 – 445938 =
830162 – 653387 =
50001 – 38562 =
72845 – 48999 =
472 x 26 =
230 x 57 =
90517 x 94 =
431 x 521 =
7643 x 843 =
9895 x 367 =
73693 x 846 =
Arme e efetue as operações com números decimais:
24,67 + 23,55 =
3,079 + 11 + 98,416 =
6,832 + 13,09 + 65,720 =
