Question

Calculeaza:
10x4:5x3+32-32:8x7=
600-56+56:8x9-50:5:10x3=
100-(42+42:6+5x3)=
(70-8x7):2+(21+21:3)=
340-(100-100:10x7+9x7)=
(80-6x9)x(163_7x9)=
(100-28):(45-36)+(4x8+9x5)=
vreau cat mai repede si cu rezolvare.

Answer 1

10×4:5×3+32-32:8×7=40:5×3+32-4×7=9×3+32-28=27+32-28=32-1=31
600-56+56:8×9-50:5:10×3=600-56+7×9-10:10×3=544+63-1=607-1=606
100-(42+42:6+5×3)=100-(42+7+15)=100-64=36
(70-8×7):2+(21+21:3)=(35-4×7)+(21+7)=(35-28)+28=7+28=35
340-(100-100:10×7+9×7)=340-(100-10×7+63)=340-(100-70+63)=340-(30+63)=340-93=433
(80-6×9)×(163-7×9)=(80-54)×(163-63)=26×100=2600
(100-28):(45-36)+(4×8+9×5)=72:9+(32+45)=8+77=85
