We're taught Brackets Others, so BODMAS. Personally I think this works, because I can't think of anything else that doesn't take priority over D/M, and it covers all of Exponents (which are the same as indices) but also surds (which are 1/indices, ie. the Nth root).

But meh, I haven't used that in years, it's all second nature to me now. You'll make lots of use of it if you go on to do Maths / Physics with all the rearranging algebra.
