Before diving in to this topic, you first need to learn about the order in which you need to carry out operations. Have you ever seen a question like the one below posted on social media?
There are usually a wide variety of answers given by various people. But how is it possible that such a simple calculation could cause so much confusion? It’s all to do with the order in which you carry out the calculations.
- If you go from left to right:
- 7 + 7 = 14
- 14 ÷ 7 = 2
- 2 + 7 = 9
- 9 × 7 = 63
- 63 − 7 = 56
The correct answer however, is actually 50. How do you arrive at this answer? You have to use the correct order of operations, sometimes called BIDMAS.
