Answer: 5mn + 5m + 4n + 4
because
2mn - 7mn = 5mn
5m = 5m
stays the same
4n = 4n
stays the same
2 + 2 = 4
if you put them toghether than you get:
5mn + 5m + 4n + 4
is equal to
2mn + 4n + 2 and 5m + 2 -7mn

If you input: 1/0.00000001 in a calculator, the result will be a very large number
so as you get closer to zero, the result of 1/x larger until it becomes infinite (or undefined as some people like to call it) at 1/0
