Elliott Fletcher commented on Dividing a polynomial with remainders, using algebraic division 7 years, 4 months ago

I think long division of numbers is something a lot of students probably students struggle with, so i think it's still worth explaining how to do it.

I could maybe split the advice into two columns, one column showing the steps of dividing the polynomial with remainders and the other column showing the equivalent steps in long division form like you mentioned in the meeting on Tuesday but i'm not really sure how to do that.

This is a very good question, there isn't really much i would change just a few minor things.

Advice

a) You don't need the "first" in the first sentence here as there is only one column for Sweet Heaven.

When you say "Similarly for Tasty Hell:" i think the colon should just be a comma but i'm not 100% sure.

b) You could maybe split up this paragraph by starting a new line after each sentence, but it's up to you.

Elliott Fletcher commented on Using Laws for Addition and Subtraction of Logarithms 7 years, 4 months ago

This looks like a good question i just have a few comments.

In the statement you might need to have a comma after you state the first law of logarithms.

Main Parts

a) good

b) are you wanting the student to input their answer as a simplified fraction or just any fraction? you might need to put in a precision restriction.

Advice

a) i) good, just a typo "subsituting" should be "substituting".

a) ii) same typo as in a) i) 

I think the have typed up the wrong questions for the advice here, i'm not sure where the a) ii) part fits in

I think the advice for a) iii) is meant to be for question a) ii) but the numbers here aren't the same as in the question.

Also you have two a) iii)s in the advice, but there are only two questions in part a) in the actual question.

b) i) you might need a full stop after the first line of maths here.

b) ii) again you might need a full stop after the first line of maths.

One of the logs here is in italics as well whereas the others aren't.

Also the final answer in the advice here is not given as a simplified fraction.
