### 2/5 — Ok but can't subtract Time

*2017-09-11*

Missing the subtraction function

**Developer response:** Thank you for your review. For subtraction, please try long tap of the plus key. Sorry for your inconvenience. In the history feature, which needs long tap of the equal key during calculation, you can change addition to subtraction.
