| - Recursion | ||
| - When the result of a method dependes on the result of the same method but called with a smaller case. You know you have a recrusive method if the method calls its self | ||
| - Recursive Case | ||
| - The expression of code where the method is calling its self |

"expression of code" is a weird term to me. Your idea is right, but seems like strange wording to me.
| - What is mystery2(-123)? | ||
| - -123 | ||
| - _Added Fun: How could we make `mystery2(-123)` work the way we might expect it to work instead of the way it does?_ | ||
| - Depends on if we want -123 to be -1 + 2 + 3 or - (1 + 2 + 3). Either case we need to add a condition that checks to see if the integer passed is negative - if true, than decided if we should take the absolute value - run the method and at the end make it negative again |

Excellent observation!! I'd want the latter, but wanted ambiguity to see what people would consider and assume.
| - 4^3 = 64 | ||
| - What is mystery4(5,0)? | ||
| - 5^0 = 1 | ||
| - NOTE: I did trace the recursions and at the end noticed the pattern of b^e :) |
| - What is mystery6("Ada Developers Academy")? | ||
| - " Academy Developers Ada" | ||
| - What is mystery6("Hi, there!")? | ||
| - " there! Hi," |

minor, but notable: there should be leading spaces at the front of each of these answers: " moon goodnight", " Academy Developers Ada", " there! Hi,"

Looks good |
