Why bother with a post grad? Are they even worth it? Have your say! 26-10-2016
1. I'm a solid A grade student but can get some occasional A* so ask away.
2. What are you tips for completing the exam paper?
3. How can I work out/estimate the median from a histogram table???
4. what do you do in algebraic equations when the numerators are numbers like 2 or 3 and the denominators are equations??

You basically make the numerators & denominators equal to eachother by multiplying them. Ie if it was 1/x+1 + 2/x+2 you would do this 1(x+2) + 2(x+1)/(x+1)(x+2) and you just simplify it. So you would get 3x+4/(x+1)(x+2)

Hope that helped ask if you need clarification.
