Question
momentum equals = mass (velocity)
yet for problems I end up using this
P = m (delta v)
what allows us to simply put the delta infront of the v to find the momentum?

Actually, (mass)x(delta V) is the CHANGE in momentum, not the momentum itself. You should write instead
(delta p) = (mass)x(delta V)
You can write it this way because the mass does not change, in most situations. One exception would be a rocket engine with mass leaving through the exhaust.
(delta p) = (mass)x(delta V)
