Question

Find the sum or difference.(Posted below)

Answer 1

thats the problem

Answer 2

You will like this problem because it is a piece of cake. You just add corresponding entries (entries in the same relative position) and make a new 2x3 matrix as the answer. For example, you will add the -8 and the -2 that are both in the upper left and that will be part of the answer. You will have 6 sets of addition to do, but they will all be simple arithmetic.

Answer 3

If that's still a little fuzzy, you will also add the "9" and the "5" and put that in the middle bottom.

Answer 4

so i just add them all together like -1 plus 0

Answer 5

Yes, that's all there is to it. It's just grouped addition.

Answer 6

ok thank you

Answer 7

You're welcome! Nice being with you again!

Answer 8

ok so i got the answers as -10 -1 5 (at the bottom) -4 14 1

Answer 9
