what do you mean by you don't understand the meaning?
you just typed it. you already simplified it for people to calculate...what exactly didn't you understand?
I'm pretty sure that it's not because you don't know what "divide" means or that you're confused with which one to divide....
I mean, you just typed the words in English and now you're saying you don't even understand what "divide" is?....it's pretty unbelievable for a 14 year old girl to do something like that, you know...
