  7. Ok guys, i saw this looking through some calculators i could use to help my grandma with her shopping list, and i found this. Why are you cheating? This is WRONG! If you really do not understand then ask a grownup for help! And you could probably ask experts here, but dont ask them for the ANSWERS! Ask them to explain something you do not understand. People who go on here to answer questions go on here to answer QUESTION! Not give the exact answers! Why don't you just ask someone for a little help?

  17. I'm pretty sure everyone on this website cheats honestly I don't need this in my life cause I'm in America? They use this in the U.K? I guess I personally won't ever use 'scientific notation' So I'd rather cheat.

  24. have u guys ever thought some people cant afford tutors, have u ever thought that some dont have no one at all to help them, have u ever thought some people are trying their best and come here for help just to check answers, have u ever thought to not always criticize ppl for coming on here, There are alot of ppl that actually have trouble understanding things and just cant get it some of you make it hard or maybe even make them feel bad about themselves then they already have. just keep the bs comments and negativity to yourself. And why are you on here if your not so-called cheating, your worried about what someone else is doing. ITS NOT YOUR WORK Or if you want them to have a tutor PAY FOR IT. And sick of the teachers that always have something to say, when u dont even want help them. Just wanna whine and complain. Instead why dont you leave your info and ask if anybody needs help. leave these kids alone. And some of you are the reason why some kids dont even wanna go to school.
