manisha singh   9 years AGO

76+76=152
then add 7 to it
152+7=159

step 1) now double the number again..
159 + 159 = 318
step 2) then add its unit place
which is 9, unit place of 159
318 + 9 = 327

repeat the 1st step : 327+327=654
repeat 2nd step : 657+7 =661

661 +661=1322
1322+1=1323

1323+1323=2646
2646+3=2649
