1. Factor out 9 and 10. You will get 3*3 and 5*2.

2. Now, do 3*2 and 5*3 and you will get 6 and 15.

3. Add 6 and 15 together and you will get 21. how to prove that 9 =886:

1. play level 886 dreamworld 9 times (and fail all 9 times).

2. play level 886 reality 5 times (pass the level 5 times  a row)

3. write the expression. 886 + 886 or 886 * 2
