In mathematical contexts, the variables ( m ) and ( n ) are often used to represent integers or indices, but they do not have specific original names. Historically, these letters were chosen for their simplicity and ease of use in algebraic expressions. In some contexts, ( m ) may represent the number of rows and ( n ) the number of columns in matrices, but otherwise, their designations can vary widely depending on the problem at hand.
I am guessing there is a missing plus sign and you want to factor mr + ns - nr - ms. If so , mr -ms + ns - nr = m(r - s) - n( r -s ) = (r - s) (m - n)
Green
(m - n)(r - s)

That factors to (m + n)(r + s) The GCF is 1.

i believe it was originally called Ethiopia
A namespace is a group of related identifiers.namespace ns {int i;double d;}Inside namespace ns, i and d can be used normally. Outside namespace ns, i is called ns::i and d is called ns::d. To import i into the current scope, say "using ns::i;". To import all identifiers in ns into the current scope, say "using namespace ns;". Namespaces can be nested:namespace ns1 {namespace ns2 {int i;}int i;}The i in namespace ns1 is fully qualified as ns1::i. The i in namespace ns2 is fully qualified as ns1::ns2::i. The two variables are distinct. Inside ns2, i refers to ns1::ns2::i; inside ns1, i refers to ns1::i.
no. it was originally called massachusetts.
This was likely miscopied, as the assortment of letters suggests environmental, which has one less M and three Ns.
There are about 9.778 miles between Halifax, NS and Sackville NS.
it was originally called Den Norske Stats Oljeselskap
