How can i add two variables?

i want the computer to perform an add instruction on two variables.


the variables are stored in binary and represent integer values. How can i work out the logic using OP tables, of adding two numbers (both in the range 0-9 for the decimal value) to get to the right answer.|||Are you looking to add the binary numbers: http://www.helpwithpcs.com/courses/addin鈥?/a>





Or are you looking to convert the numbers to an integer and then add them?





What langauge are you using?
