@LaurenAshley1201 You can also use Wolfram Alpha as well, it will solve equations for you in seconds and will show you with steps on how to get your answer.

10. RyanL.

You should only do that to check your work not to get answer.

11. RyanL.

You can't use wolfram in test so don't rely on it.

@RyanL. Of course, it's just useful. I live in a different time zone from most people on here and sometimes nobody is online when I ask a question!
