It's an online class and I have a learning disability in math, thank you.

So unfortunately for me, I don't understand math as easily as everyone else does, especially if it involves fractions.

Answer 13

Answer 14

Answer 15

@jendearest16 ur fine. @nincompoop is being rude. Plus most of the questions u had answers for were right

Answer 16

How was I being rude? She posts one question after another, so that makes me wonder if she is putting effort in learning at all or is relying on other people completely? This affair is not conducive to her intellectual growth; not in any way

Answer 17

well @nincompoop she can post as many question as she wants to. As long as she has an idea in which she does. Every single question I answer for her she already has an idea of the answer and 99.9% of the time shes right. What do you think open study is for then?(rhetorical question). Jeez calm down

Answer 18

it's similar to the way you did it last time. you found the right answer. And does it really matter. like if she just asks for the answer, then that's a different story, but she tries to comprehend it as much as she can. chill dude. this is a place where you ask for help. and i've seen people ask question after question and don't care for an explanation.

Answer 19

And by knowledge shall the chambers be filled with all precious and pleasant riches.

Answer 20

And yes, it matters

Answer 21

@ jendearest16
