IB Mathematics HL – Vectors operations, addition, subtraction, scalar multiplication


First of all let me remind you the properties of vector addition

The vector addition (subtraction) is Commutative, Associative, there is an additive identity which is the zero vector ad there is an additive inverse which is the vector with equal magnitude and opposite direction. Also there is the scalar multiplication which is when a vector is multiplied by a scalar.

So about your question we have the following











and










Hope these help!
