[7 6] +[3 8]

Sorry this is the only way I know haw to put matrices on the board.

Answer 1

Yes, the numbers in a matrix can have any value, positive or negative, fractions, decimals and irrational numbers, not just integers from 0 to 9. They can also be complex numbers like 4 + 3.1 i

[3 4] +[2 7] = [5 11] , for example
