>> 789*4567
ans =
3603363
I want to add each element of the ans :
i.e., >> 3+6+0+3+3+6+3
ans =
24
Help me how to do this?

Lots of ways...just a couple--
>> sum(str2num(num2str(789*4567).'))
ans =
24
>> >> sum(sscanf(num2str(789*4567),'%1d'))
ans =
24
>>

Try this:
theNumber = 3603363
theString = num2str(theNumber)
theSum = sum(theString - '0')
(I hope I didn't just do your homework.)
