Multiplying column vectors

Multiplying vectors is just like any normal calculation but keep the top row separate from the bottom row. This is sometimes called scaling a vector. A scale has magnitude (size) only but in terms of scaling a vector you can think of scaling as a multiple.

Scalar = Multiply 

Scaling is the same as multiplying when it comes to vectors

Example 1

Multiply vector (32)  by 3

(32)×3=(3×32×3)=(96)

Answer:

The vector (32) multiplied by 3  is (96)

 

Example 2

Scale the vector (32)  by 3

(32)×3=(3×32×3)=(96)

Answer:

The vector (32) scaled by 3  is (96)

 

Example 3

What is half of the vector (26)

(26)×12=(2×126×12)=(13)

Answer:

Half of the vector (26)=(13)

 

Example 4

What is half of  the vector (-46)

(-46)×12=(-4×126×12)=(-23)

Answer:

Half of the vector (-46)=(-23)
