Question

Verifică egalităţile:
• 12 x 3 x 10 - (100 + 35:5) = 50 x 2 + 25 x 4+ (309 – 200 - 8 x 7);
. 136 - (9 x 9 +5 x 6) = 450 – (320+6x7 - 3 x 8).​

Answer 1

1.  12 x 3 x 10 - (100 + 35:5) = 50 x 2 + 25 x 4+ (309 – 200 - 8 x 7)

360-(100+7)=100+100+(109-56)

360-107=200+53

253=253 sunt egale

2.   136 - (9 x 9 +5 x 6) = 450 – (320+6x7 - 3 x 8)

136-(81+30)=450-(320+42-24)

136-111=450-(362-24)

25=450-338

25=112 nu sunt egale
