[VECTORS] Calculating the projection of a vecton on other

Hi! i,m studying vectory operations from a book for 3D graphic.
In this paragraph is reported a formula

I need help to know how in a real problem, should sobstitute the n and v in the formula. For exemple v=[5,3] n=[2,0]
So let's calculate Vii= n ( (v*n)/|v|^"2) )

ok, i know how calculate the |v| (it's the magnitude), but what rapresents n and v ??

Maybe i've to calculate the value twice sobstituting each time n1 v1(2 & 5) with n2 e v2 (0 & 2) ?
