Question

How do you simplify `8[(0.25,0.5),(0.75,1.5)]-2[(0.25,0.5), (0.75,1.5)]`?

Answer 1

Using the normal associative property of addition.

Explanation:

Because the matrices are not only of equal size, but identical, the multiplying coefficients may be combined first.

`8[(0.25,0.5),(0.75,1.5)]-2[(0.25,0.5), (0.75,1.5)]` = `6[(0.25,0.5),(0.75,1.5)]`
