Question

Calculează, respectând regulile învățate:
(8 - 6 ) × (9 – 4) =
100 : 10 (6 + 4) =
(7 – 7) 7 + 2 x 2 x 2 =
(18 – 9): 3+ (4 + 5) x 2 =​

Answer 1

Răspuns:

1. 2 × 5 = 10

2. 10 × 10 = 100

3. 0 × 7 + 8 = 8

4. 9 : 3 + 9 × 2 = 3 + 18 = 21

Answer 2

Răspuns:

(8-6)×(9-4)= 2×5=10

100:10(6+4) = 100:10×10= 10×10=100

(7-7)7+2×2×2= 0×7+2×2×2= 0+8=8

(18-9):3+(4+5)×2= 9:3+9×2= 3+18=21
