Most about translation in english for a software

Hi folks !

I am (slowly) developing a software creating elementary maths exercises and the matching solutions (expand and reduce algebraic expressions, solve equations of 1st degree, calculate the length of the hypotenuse by pythagorean theorem etc.). I write it in english but I am absolutely not a native speacker ! So sometimes when I don't find it elsewhere in internet (wikipedia etc.) I need some help to find the correct way to write some sentences related to specific maths words and expressions.

Actually I already posted in this forum some years ago and had nice answers but the matching threads have been removed apparently. It doesn't matter, but in the case I would like to ask this kind of question, which place would be the best ?

And well I am a math teacher in France for pupils from 11 to 14 years old.

Have a nice day !

Nicolas
