### 2/5 — Meh

*2021-07-08*

As a math teacher, I like the framing “find all the expressions that equal [whatever]”. However, that’s the only prompt for the entire app. Also, the app gives no feedback AT ALL—much less corrective feedback. 

Also, it only does addition and subtraction. It wouldn’t be too much more coding to implement addition or subtraction.
