It's a magic number trick where I have to write an algebraic expression for each step of the trick using "n" as the number.
1. Pick any number
2.Multiply by 3
3. Add 30
4. Divide by 3
5. Subtract your original number
I started the expression but I get stuck at step 4. So here is what I have
1. n
2. (n x 3)
3. (n x 3) + 30
Any help would be appreciated.
