216 x 4= 864
421 x 2 - 81 : 9= 842 - 9= 833
52 x 4 + 17 = 208 + 17= 225
5 x 100 + 84= 500 + 84=584
24 + 2 x 512= 24+ 1024= 1048
(60-4x8)x(50-6x7)=(60-32)x(50-42)=28x8=224
8x9-18:3+6x9-4x7=72-6+54-28=66+54-28=120-28=92
40:5+63:7+6x8=8+9+48=17+48=65
100-30:5x8-6x4:3=100-6x8-24:3=100-48-8=52-8=44
89+64:8x7-28:7x4=89+8x7-4x4=89+56-16=145-16=129
