x=1: Learn to solve equations

2021年06月23日

Mathematical regards,

lot's of improvements coming your way!

* Zero +- a term from the other side of the equation is now calculated immediately
* The expansion of the selection is now a tad faster. Keep me updated if this feels good
* The "multiply with -1" button is finally here. Equation played until -x=-1 are no longer cumbersome so solve!

Please tell me any problem you see, so I can fix it as soon as possible: https://twitter.com/xgleich1
