SOLUTION: I am trying to solve the problem: ln(x)-ln(2)=10
the way I thought this was supposed to be handled was:
1. ln(x)-ln(2)=10
2. ln(x-2)=10
3. ln(x-2)= e10
4. x-2=e10
5. x=e10+2

From
ln(x)-ln(2)=10
I would combine logs first...
ln(x/2) = 10
then exponentiate
(x/2) = e^10
then multiply by 2
x = 2e^10 = 44052.9
