BEDMAS says you do multiplication before addition, so it's 10.
The one I learnt at the dawn of time was BODMAS.
bracket of Division Multiplication Addition Subtraction.
I learnt this in the 70's early 80's in South Africa, so not sure if things have changed.
B/P are the same (brackets/parentheses) and O/E are the same (order/exponent), and the order of M and D doesn't matter since those two have equal priority and are evaluated left-to-right. Hence PEMDAS, BODMAS, BEDMAS, etc. are all the same.
