PEMDAS Mathematical order of operations. Parenthesis, exponent, multiply, divide, add, subtract. I only learnt this a year ago and it's almost embarrassing how much my maths or ability to understand math has improved from this(I'm 28 and never gotten taught this in schools general maths so I used to find math really difficult).

To complete the picture, you might've been taught a completely different mnemonic in other countries. The one I was taught was BODMAS ( "B"rackets, "O"f or "O"rder, "D"ivision, "M"ultiplication, "A"ddition and "S"ubtraction) and some African countries teach this as BIDMAS [0]. Caused a lot of confusion when I came to the US and drew a blank when someone mentioned PEMDAS in an example.

I'm curious, where did you go to school. I remember learning PEMDAS in 6th grade (New York State) and it's been burnt into my brain since.

Australia, mid price private school in the country. I was blown away to have never had it expressed during school after learning it.

How come it was never taught?
