No, subtraction is not commutative.

#### Work Step by Step

Subtraction is not commutative so the order that the equation is in makes a difference for the answer. If you apply values to the vectors, you can see how the order of their subtraction matters. Example: a=5 b=10 a-b (5)-(10)=-5 b-a (10)-(5)=5 -5$\ne$5
