Here is the free online vector subtraction calculator to find the difference between two 3D vectors, for the given values. Subtraction of 2 vectors is nothing but subtracting the corresponding co-ordinates of one vector with the other, which could be denoted as ci = ai – bi.

For example, consider two vectors a=[3,7,2] and b=[-8,3,2].

a - b = (3-(-8)),(7-3),(2-2)

=(11i+4j)
