137+276=435,how it comes means 7+6=13 but in hundreth place 5 is there
so 13-8=5.but in 13 keep a carry.then, 1+7+3=11,so 11-8=3 but in 11 keep the carry up.then,1+1+2=4 so the answer is 435.
in same way,731+672=1423
how it came means,1+2=3.then,7+3=10 but 10-8=2,keep the carry up.
1+7+6=14.but 14-8=6 but keep the carry up.so,1 will come atlast
so answer is 1623
731+672=1623

Is this solution Helpfull? Yes (2) | No (3)  

shekhar deshpande  (10 years ago)

ans is 1480
137+276=413,but it has given 435,i.e(435-413)=22
but 2+2 is 4 which is hundred's unit of answer
so, 731+672=1403 but according to above logic hundred's digit is 14
therefore 7+7=14,which gives addition of 77 to number
so 1403+77=1480.
