 Nabanita Sarkar said: (Jul 4, 2014) This is so simple to add numbers, there are small numbers. But my solution can help to solve big numbers also. We know that 17*2 = 34, So 0.017+.0.617 = 0.634, Now 40+17 = 57, so 0.6340+0.0017 = 0.6357. 6*2=12 and 12+17=29,[where 17 is the last two digits of 617 ] So, the answers is 629.6357.
