Now, you might be reciting the famous DMAS rule under your breath as you try to figure out your next move. This basic math problem went viral in Japan after a study concluded that a mere 60 percent of the population in their 20s could actually figure out the right answer.

If anything, the human mind is slowing down because a previous study, conducted way back in the 80s found a massive 90 percent 20-year-olds who gave the right answer.

Well, it so happens that the very tool you are using, the DMAS rule is to blame. While the DMAS rule dictates that you divide 3 by 1/3 and equate it to 1, the actual method requires you to convert the sign of division into multiplication by taking a reciprocal. Thus, you will end up with 9 in the middle whereby the equation looks quite simple to solve.

Yet, this is not the end of your troubles. You might again refer to DMAS and decide that you need to solve the sign of addition before you tackle the minus sign, the middle term takes preference. Thereby, you can work your way to a simple and elegant answer of 1.
