Missing parentheses when multiplying with a negative number #240

Open Stumblefeet opened 6 years ago

Stumblefeet commented 6 years ago

A well-formed formula does not allow for a multiplication sign to be followed by a minus sign.

I recently tried 2-5(3-6) and got 2-5-3

Thank you for noticing this an opening an issue!

I'm not actively working on mathsteps right now, but am happy to help you make a PR to update this :)

Seems like there would need to be an update to the removeUnecessaryParens function, but that could be messy and break some other functionality. Would be interesting to explore!

Thanks.

I'm considering diving into the code and study it in depth.

Do you know if this project is still being developed, or is it dying/finished?

I'm looking for a large project to contribute to, and this seems rather nice.

evykassirer commented 6 years ago

I haven't been prioritizing much time on mathsteps lately, so it is some ways dying.

However, if you take a look through the code and would like me to answer some questions or help you contribute, I'd be happy to spend some time on that :)

@evykassirer I am personally interested in helping out. mathsteps should not die. It has tremendous value and potential ! Is there a priority list somewhere with things pending ?

evykassirer commented 6 years ago

the list of open issues is a good place to look for things pending!
