Balancing Carry Over 13|56|01|9 first balance it 13|56|01|09 ______________ =18619 write 9 then 0+1=1, 0+6=6,5+3=8 write 1 Start the method from right hand side. 8 |86|08|65|8|8 balance 08|86|08|65|08|08 =1674588
RACY SUBTRACTION 78890765326 -66569999996 ----------------------=12320165330 123 3 ( 0-9=-9) 20(10-9)next no.is 7-9 165330 Same method as Racy Addition but instead of adding 1 when the next no. Is a big number subtracted from small (3-9=-6) subtract 1 from the previous number . 75899764333679 - 58843213489008 ____________________ 16956550844671 POWER 10 SUBTRACTION If there are zero in above no. Subtract all zero from 9 and the last one from 10. Example 63000000 -49784200 ____________=13215800 13 (9-7=2) (9-8=1) (9-4=5) (10-2=8) 00 40000005 -29747898 ___________ 10252107
