Dear Guochao Wang,

Thank you for your question.

The reason why you get this result, is because the real operator that is implemented in our math solver is `x+y%`

, thus taking precedence over the multiplication.

We have chosen to define the `x+y%`

operator that translates to `x+x*y/100`

.

This allows you to write `120+10%=132`

, which is what is usually expected in everyday life, for a calculator use.

Best regards,

Gwenaëlle

I'm new in MyScript and just found the wrongs of this APP in its math basics as shown in the attached file.

while I am looking for some answers and solutions, I suddenly realised that the last update of this APP in Apple's App Store was 1 year ago.

SO, not sure either the crew is still working on and keep regular updates of MrScript or you by any chance will see this post.
