Explicație pas cu pas:
a) [(36 + 4): (40:4)] x 2
[(36 + 4) : (40 : 4)] x 2 = 8
= ( 40 : 10 ) x 2 =
= 4 x 2 =
= 8

b. [(96-32) × (37 + 19)]: 2
[(96-32) × (37 + 19)] : 2 = 1 792
= ( 64 × 56) : 2 =
= 3 584 : 2 =
= 1 792

c.[(64 +36) x (64-36)]: 4
[(64 +36) x (64-36)] : 4 = 700
= ( 100 x 28 ) : 4 =
= 2 800 : 4 =
= 700
