Question

(7x7+7:7)x7, (20:2+28)x2, (18x2+18):6, 196-3x(89-45), 1000-(35+60x2)+40, 999+(10:2x4)-501, 50+(40+80x100)-50

Answer 1

(7x7+7:7)x7
(49+1)x7
50x7 = 350

(20:2+28)x2
(10+ 28 ) x2
38x2= 76

(18x2+18):6
(36+18):6
54:6=9

196-3x(89-45)
196-3x44
196-132=64

1000-(35+60x2)+40
1000-(35+120)+40
1000-155 +40
845+40=885

999+(10:2x4)-501
999+(5x4)-501
999+20-501
1019-501=518

50+(40+80x100)-50
50+(40+8000)-50
50+8040-50
8090-50=8040
