 This is true: `for entry in math_iter` is much simpler than `while let Some(entry) = math_iter.next()`. And a `for` loop is actually an iterator so we don't have any reason to write `.iter()`. Thanks, clippy! And also we didn't need to make `math_iter`: we can just write `for entry in result_vec`.
 
-And the second point is true too: `if adds == true` can just be `if adds` (because `adds` = `true`).
-
 Now we'll start some real refactoring. Instead of separate variables, we will create a `Calculator` struct. This will have all the variables we used together. We will change two names to make it more clear. `result_vec` will become `results`, and `push_string` will become `current_input` (current means "now"). And so far it only has one method: new.
