Question

verifica egalitatile: 12x3x10-(100+35:5)=50x2+25x4+(309-200-8x7); 136-(9x9+5x6)=450-(320+6x7-3x8). Ordinea efectuarii operatiilor si folosirea parantezelor rotunde

Answer 1

12•3•10-(100+35:5)=50•2+25•
•4+(309-200-8•7)
360-107=100+100+53
253=253 (A)

136-(9•9+5•6)=450-(320+6•7-
-3•8)
136-111=450-334
25=116 (F)
