Explicatie pas cu pas:

ex 5

Primul mod : (32 - 16 - 8) : 8 = (16 - 8) : 8 = 8 : 8 = 1

Al doilea mod : (32 - 16 - 8) : 8 = 32 : 8 - 16 : 8 - 8 : 8 = 4 - 2 - 1 = 2 - 1 = 1

_______________________

ex 6

13 + 24 - 8 × a = 10 : 2

37 - 8 × a = 5

8 × a = 37 - 5

8 × a = 32

a = 32 : 8 = 4

Verificare : 13 + 24 - 8 × 4 = 10 : 2

13 + 24 - 32 = 5

37 - 32 = 5

5 = 5
