In the video it says that in bodmas the O stands for order but in our school we have learned that it stands for of , Why? What is the difference
When any part of an expression is inserted within a pair of brackets with a negative sign before it, the sign of each term inside the brackets remains unchanged.
For a question like A U B intersection C, if no brackets are specified, how do you approach. Is there a rule such as BODMAS for Operations on Sets also?
