For this kind of problem, you need to understand, for example, +10% is the same as multiplying by 1.1. If 2 years go by, instead of +10% and +10%, you can use an exponent of 2 and get $\"1.1%5E2=1.21\"$ . Similarly, dropping or losing 10% would produce a multiplying by .9. Saying -10% is the same as multiply by .9. \r
