Hi to all!
I have made a new proof assistant inspired from metamath but much close to classical math.
On
mmex.app you can find 2 proven formulas:
(a+b)^2 and quadratic equation.
For the moment you can only see the proof or you can reprove again the formula(new formulas cannot added from now but in the future: yes)
After entering on
mmex.app go to: Content , then to : Proven formulas and then you will find the 2 formulas.
Base formulas are built-in (coded in javascript) like: calulations, give a common factor, add exponents on a product of powers with same base, etc......but are also proven formulas that can act as a built-in formulas.
If you have some time to take a look on my site it will be wonderfull.....
Have a nice day!
