9x2+8x7-(83-54)=

9x2=18

8x7=56

(83-54)=29 ( parantezele se elimina)

= 18+56+29

= 45

--------------

7+42:6+19+58+7=

42:6=7

7+7+19+58+7=98

------------

9x4+54:9+28-8

9x4=36

36+54:9+28-8

54:9=6

36+6+28-8

= 62

---------------

85-9x4+7+4-7x4

9x4=36

85-36+7+4-7x4

7x4=28

85-36+7+4-28

= 32

--------------

3:3x9+ 18:2-2x4=

3:3=1

1x9+18:2-2x4

18:2=9

1x9+9-2x4

2x4=8

1x9+9-8

orice expresie inmultita cu 1 ramane neschimbata

9+9-8

= 10

66-35-5x2+27 +22=

5x2=10

66-35-10+27+22

= 70

65-3-36:4+34-23=

36:4=9

65-3-9+34-23

= 64

---------------

15+43-8+8:2+9x5=

8:2= 4

15+43-8+4+9x5

9x5=45

15+43-8+4+45

= 99

-------------

34+51-24:4x5+23=

24:4x5=30
