Either a new subject on this topic, a class on it within each course/grade, or a simple revision to how things are worded.

Hello, I've been using Khan Academy for quite some time now and it's worked fairly well. I have noticed however that a lot of the time when I get an answer wrong it is simply because the questions have either

1. Been worded poorly
2. I've been given a question I know the answer to but don't know how to input it correctly into the box given

One of the hardest things for me is understanding the phrasing of a question and I would love a course/class or simple description bubble under each question explaining how/why educational questions are worded this way, how to properly deconstruct them and what the correct input is into things.

I have an example here -

I know what the value is, it's in the value place of a one. However, I had to think long and hard about how it wanted me to indicate this, and I still got it wrong. I put 1, it wanted 6 - because it represents 6. Thinking on it now, it makes sense but at the time I was too busy trying to think of what to input.

Anyway, it's just a thought, I'm still studying hard every day but sometimes little things like these can frustrate me, as I know the answer and that my answer was correct the first time but because I input it wrong -  I got it wrong.
