BOMDAS implies that you do multiplication before division and addition before subtraction.
This is not the case, it's a result of poor teaching. Multiplication and division have equal priority and must be done in the order that they appear in the equation (starting from the left). In this case therefore you divide 48 by 2 before multiplying the answer by 12.
Yes, it's another thing we were all taught incorrectly in school.
It's explained very clearly and correctly in school maths textbooks. Perhaps it was taught poorly to a lot of people but I find it hard to believe it was taught incorrectly by that many teachers.
Also, if you google you will see that this question has been debated on many forums for several years by people from many nationalities. Obviously the confusion is not just down to incorrect teaching here in Ireland.
