When, in algebra, two letters are written next to each other as a term, such as m and n becoming mn, it means they are multiplied. So mn is a shorter way of writing "m times n" or "m x n"Therefore, when m = 1 and n = 1, mn = 1 x 1 = 1
Commutative
no
Yes.
m + n = 10000.05m + 0.06n = 57

m(n + 1)

Yes.
mn - 15 + 3m - 5n Rearranging: mn + 3m - 5n - 15 = m(n + 3) - 5(n + 3) = (m - 5)*(n + 3)
mn - 4m - 5n + 20 = (mn - 5n) - (4m - 20) = n(m - 5) - 4(m - 5) = (m -5)(n - 4)
m + n = 10000.05m + 0.06n = 57
Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "equals" etc. Some possibilities are: mn + mp + 3nq + 3pq = (m+3q)*(n+p) mn - mp - 3nq + 3pq = (m-3q)*(n-p) mn + mp - 3nq - 3pq = (m-3q)*(n+p) mn - mp + 3nq - 3pq = (m+3q)*(n-p) If your question is for something else, please resubmit your question spelling out the symbols as "plus", "minus", "equals" etc.
(m - 5)(n - 4)
87
It would be the same number either way because its addition.
