This is done by a combination of AND and OR circuits. Do some reading on "half adder" and "full adder" to get an introduction of how these circuits work. For example here: http://en.wikipedia.org/wiki/Adder_(electronics)

In a real computer, in the simplest case two integers, each consisting of several bits, are added; this requires several half adders and full adders to be connected, one after the other.

The actual computer circuits are more complicated than that, because of a Need for Speed. Also, the addition of "real numbers" (basically, numbers in scientific notation), often used on computers, is much more complicated than the addition of integers.
