Answer 1

Răspuns:

a) (18+27):(12:2+8:4)=8

18 +27 =45

45:(12:2+8:4)=8

12:2+8:4=8

12:2=6

8:4=2

6+2=8

Answer 2

Răspuns:

$(18 + 14) \div (6 + 2) = 32 \div 8 = 4$

$24 - 8 \times (8 - 6) \div 4 \times 5 = 24 - 8 \times 2 \div 4 \times 5 = 24 - 16 \div 4 \times 5 = 24 - 4 \times 5 = 24 - 20 = 4$

$6 + 8 \times 5 - (20 - 4) = 6 + 40 - 16 = 46 - 16 = 30$

$6 + 12 \div 2 - 24 \div 8 = 6 + 6 - 3 = 9$

$45 \div 5 - 24 \div 8 = 9 - 3 = 6$

$10 + (1 + 10) - (10 + 10) = 10 + 11 - 20 = 21 - 20 = 1$
