You don't even need that, since you have a number before your matrix that tells you how big it is. Simply add second number after that, do some sort of while/for/do-while/goto loop (ok, maybe only while or for :) ) and it should work. If you want more help, post your attempt (that is, attempt to read more
matrices
, not just one)

Thank you :) The only problem I'm having now is more of a cosmetic issue. When I output my
matrices
, even though it outputs 0.00, I think in some cases it's not exactly 0. Because, some of them output as -0.00. Is there a way to fix this issue? Should I worry about actually making those values equal to 0?

If you had paid attention in math class you'd have known how to multiply
matrices
. If you had paid attention in programming class you'd have known how to write basic Java programs like this. If you'd had half a brain you'd have figured out how to combine those two bits of knowledge.
