DBRS Process for Changing the subject of a formula
I promised I would post this! I have now presented about the process of Decide, Break, Repair and Simplify at Bristol and Sheffield maths conferences for changing the subject of a formula. This has been a pleasure and has been received incredibly well by a lot of maths teachers across the country.

However, during my presentation I mentioned how I have got around this problem with slides like below:
