 1.  Remove the parts of the question string that do not apply to calculating the answer.
 2.  Iterate over the question, determining which words are numbers, and which are meant to be mathematical operations.

 3.  **_Starting from the left_**,  take the first three elements and convert number strings to `int` and operations words to the mathematical operations +, -, *, and /.
 4. Apply the operation to the numbers, which should result in a single number.

 5. Use the calculated number from step 4 as the start for the next "trio" (_number, operation, number_) in the question. The calculated number + the remainder of the question becomes the question being worked on in the next iteration.

 6.  Once the question is calculated down to a single number, that is the answer.  Anything else that happens in the loop/iteration or within the accumulated result is a `ValueError("syntax error")`.
