To combine bitmasks you want to use bitwise- or. In the trivial case where every value you combine has exactly 1 bit on (like your example), it's equivalent to adding them. If you have overlapping bits however, or 'ing them handles the case gracefully. To decode the bitmasks you and your value with a mask, like so:
