lim f(x) = L x -> c
lim g(x) = M x -> c
lim(f(x) + g(x)) = L + M Sum property of limits x -> c
lim(f(x) - g(x)) = L - M Difference property of limits x -> c
lim(f(x) * g(x)) = L * M
x -> c
lim kf(x) = k * L Constant multiple property x -> c
lim Quotient property x -> c
lim(f(x)) Exponent property x -> c
works as long as r and s are integers
