équation-bilan (3 listes)

You practice adjusting balance equations using my software available here:

the "equation" software generates a qrcode.

you can collect all student results by scanning their qrcode with this android application.

This version is limited to 3 simultaneous student lists. I will make a premium version soon. This version is perfectly functional and may be sufficient. The purchase of the premium version is mainly to help me and thank me.
