This post is getting a lot of traffic. Here are the main points of the video in text. There are two ways to interpret the question. If you evaluate the 2(3) term first, then you get 10. 62÷ 2(3) + 4 = 62÷ 6 + 4 = 6 + 4 = 10 You could also say the brackets are like multiplication, so you’re dividing by 2 and then multiplying by 3. In that case you get 58. 62÷ 2(3) + 4 = 36 ÷ 2(3) + 4 = 18(3) + 4 = 54 + 4 = 58 Which interpretation is correct? Let’s check an online calculator WolframAlpha. If you input the expression, you’ll get an answer of 58. Here’s a link where you can see for yourself: 6^2 ÷ 2(3) + 4. The same thing happens if you type the equation into Google. You also get an answer of 58. The calculators interpret the order of operationsto mean the parenthesis are like multiplication. So we should evaluate 6^2, then we should divide by 2, then multiply by 3, and finally add 4. This means the answer is 58. The larger point is the expression is written ambiguously. If we need to divide by 2(3), then it should read 62÷ (2(3)) + 4 It’s like trying to interpret the following sentence: “I saw the man with binoculars.” Did you use binoculars to see the man, or were you looking at the man who was holding binoculars? In math we avoid this kind of ambiguity by following conventions and writing expressions clearly. The best interpretation is 62÷ 2(3) + 4 = 58, but it would be better if the expression was not written in a confusing way. Nasir raisani
