1.25 X( 8+10)
=1.25X 8+1.25X 10
=10+12.5=22.5
9123- (123+8.8)
=9123-123-8.8
=9000-8.8
=8991.2
1.24 X 8.3+8.3 X 1.76
=8.3X( 1.24+1.76)
=8.3X 3=24.9
9999X1001
=9999X( 1000+1 )
=9999X 1000+9999 X 1
=10008999
14.8 X 6.3-6.3 X 6.5+ 8.3 X 3.7
=(14.8-6.5)X 6.3 + 8.3X 3.7
=8.3X 6.3+8.3 X 3.7
8.3 X( 6.3+ 3.7)
=8.3X 10
=83
1.24+0.78+8.76
=(1.24+8.76) +0.78
=10+0.78
=10.78
933-157-43
=933- (157+43)
=933-200
=733
4821-998
=4821-1000+2
=3823
I32 X 125 X 25
=4X 8X 125 X 25
=(4X 25)X(
8X 125)
=100X1000
=100000
9048 - 268
=(2600+2600+2600+1248)- 26
=2600 - 26+2600 - 26+2600 - 26+1248 - 269
=100+100+100+48
=348
2881 - 43
=(1290+1591)- 434
=1290-43+1591 - 43[-3]+[-2]+[-1]+0+1+2= -3
=30+37
3.2 X 42.3 X 3.75-12.5 X 0.423 X 16
=3.2X 42.3 X 3.75-1.25X 42.3 X 1.6
=42.3 X (3.2 X 3.75-1.25 X
1.6)
=42.3 X (4 X 0.8 X 3.75-1.25 X 4 X 0.4)
