on here i need some help for solving some math example.
let's get over it!!
I have absolutely no idea what that means! In fact, although I am sure you did not mean it, in English, "Let's get over it" comes across as something of an insult.
In any case, don't just tell us you have a problem, tell us what the problem is! And be sure to include all the work that you have done on it so we will know where, exactly, you have a problem and what hints will help.
