Hi Stanislav,

I think for part c) and d) you could rearrange the format for inputting answers into an actual fraction with gap fills included. Then it will match the form of the question when it is asked and might make it easier to understand. I have included this in some of my questions so if you are not sure how to do this, I can show you.

If your expression is $\displaystyle\frac{\frac{(x-a)}{b}+c}{bd}$, rearrange it to $\displaystyle\frac{x-a+bc}{bd}$. Type this into the marking box as      

(x+{-a+b*c})/{b*d} and it should simplify nicely.

In all parts of the question, put $\=$ after the expression and before the answer box.

In the advice, make sure a), b) etc are in heading 4 and that your solutions begin on the next line down. Anywhere that you reference an earlier part, write it as a) rather than a. You should write solutions for all subparts, although I agree that only subpart i) needs to go into detail. 

In part d) of the advice, make sure that when you take the square root you find $\pm$ answer, which you can do by using \pm. The last lines of this section aren't rendering so have a look at that.

When I tried part c), the solution in the advice came up with a recurring decimal, although this only happens some of the time. I'd fix this so that Numbas produces a fraction instead, which should happen if you use the \simplify command. 

Also ensure all of your equations in the advice display in the centre of the screen.

Sorry, the final sentences are meant to read:

To find $25$% we can multiply by $0.25$. To increase something by $10$%, we can multiply by $1.1$.

Parts b) and d) are testing subtraction rather than percentages so remove these parts. If you wanted to bulk out questions you could combine the ideas in parts a), c) and d) into a single question. Some questions giving the new price after the percentage change and asking students to calculate the old price would be good here to demonstrate that it matters which number you take the percentage of (this often confuses students). It would also be a good idea to have students calculate the percentage change bewteen two prices.

In the advice, I would include mulipliers as one of your possible methods for calculating percentages. For example, to find $25%$ we can mulitply by $0.25$. To increase something by $10%$, we can multiply by $1.1$.

In the advice you say '295 rounded to the nearest ten is 300 and NOT 2100'. I don't think this is a common mistake! I would remove this line and instead explain that sometimes the nearest ten is also the nearest hundred. You should add an extra question at the very start where the nearest ten is not also the nearest hundred. 

When adding subparts to questions, you don't need a full stop and a parenthesis. Just use the parenthesis.
