Matrix multiplications are defined if the number of columns in the first matrix is equal to the number of rows in the second matrix.
Multiply the first element of the array by the first element of the second array to get the element of the first row of the first column in the product array.
The remaining elements of the product matrix are obtained in the same way.
Simplify each item by multiplying the individual terms.

Answer:
The opposite of 14 is -14.
Step-by-step explanation:
Opposites are numbers with the same distance from 0 but one is to the right of 0 and the other is to the left of 0.
The opposite of 0 is itself,0.
So the opposite of 5 is -5 since both 5 and -5 have the same distance from 0 and one is to the left and one is to the right of 0.
The opposite of 14 is -14 since both have the same distance from 0 and one is to the right and one is to the left of 0.
You can also think of this question as what can I add to 14 that will give me 0.
The answer is -14 since -14+14=0.
Another word for opposites is additive inverses. When you add additive inverses you get 0.
Another example: What is the opposite of -16?
The answer is 16 since 16+(-16)=0.
