Use BIDMAS to answer 2 + 7 x 10

Using BIDMAS we know that we should do multiplication before addition and therefore we would get, 7 x 10 which is 70 and then 2 + 70 which is 72.This is really important to have rule about orders of operations because there cannot be more than one answer to a calculation like this.
