### Answer:

( 4.5, x_{1}, w ) + ( -2.3, 3, y_{2} ) = ( 2.2, x_{1}+3, w+y_{2} )

# Matrix Subtraction

Two matrices of the same type can be subtracted to produce a third matrix
of the same type.
As you probably imagine,
subtracting two matrices means subtracting the corresponding elements,
*being careful to keep the elements in the same order:*

(10, 8, 12 ) - (2, 14, 9 ) = ( 10 - 2, 8 - 14, 12 - 9 ) = ( 8, -6, 3 )

If **a** and **b**
are matrices of the same type,
**a** - **b** = **c**
means that each element c_{i} = a_{i} - b_{i}

### QUESTION 9:

Do these two problems:

(22, 5, -12 ) - (10, -5, 3 ) =
(10, -5, 3 ) - (22, 5, -12 ) =
