10×4÷5×3+32-32:8×7=24+4=28
600-56+56÷8×9-50÷5÷10×3=544+63-3=604
100-(42+42÷6+5×3)=100-(42+7+15)=100-34=66
(70-8×7)÷2+(21+21÷3)=7+28=35
340-(100-100÷10×7+9×7)=340-(100-133)=340-(-33)=340+33=373
(80-6×9)×(163-7×9)=(80-54)×(163-63)=26×100=2600
(100-28)÷(45-36)+(4×8+5×9)÷7=72÷9+77=8+77=85
sper ca te am ajutat
