Practice makes perfect

For the addition of matrices to be possible, they need to have the same dimensions. In the given exercise, both are 2* 3 matrices. This means they both have two rows and two columns. To add these matrices, we add the corresponding elements. Let's do it!

0&-1 &5 6 & 10&12 + 9&-5 &7 -4& 10&0
