Math Help - adding velocities

Hi
Lets say i have two Y velocities, 37,6 and 100.
How do i add them together?
37,6 + 100 = 137,6?

Oh, no matter.
I had an unwanted pair of brackets in my formula wich made it produce uncorrect results wich in turn led me to believe that i was doing somthing wrong in the formula ( adding velocities wrong or something ).
I removed the pair of brackets and now everything works fine

Velocities are added by simple adding them normaly like you would with any two regular numbers.

Provided they are numbers. If they are vectors, you need to add "vectorially" or "component wise", not just add the "speeds", the magnitudes of the veloctity vectors.
