You solve the expression inside grouping symbols such as brackets first, then do exponents and roots, then multiply and divide, and finally add and subtract. It seemed wrong to do whatever a person thought was right when they have to solve something like (3 + 2) x 3 – 4 ÷ 8… There had to be a standard way of getting through it, and that’s how PEMDAS was born. PEMDAS became a convention when people needed a generally approved method of solving expressions containing multiple operations. They also came up with groupings for clarity such as parentheses and fractional terms. How to undo this? Take the root of the operation. Over time, there was a need for faster multiplication, and people came up with exponents. There had to be a way to undo this operation and hence came division.įor centuries, the only thing people did as math was adding, subtracting, multiplying, and dividing. They went ahead to invent a method for adding the same repeated number at a faster rate, and multiplication was born. However, these two operations were simply insufficient. They could lump two groups of sheep together to make one whole group, or remove a few tubers from a heap of crops to have less. Of courses, the only thing they could initially do was to add and subtract. For instance, the Babylonians worked with a system based on 60, while most others took their measurements in 10s. Many communities invented their own systems of counting. As early as the 6 th Century BC, people needed math to keep count of their animals, crops, and carry out trades. While the actual origin and inventors have remained unknown for decades, historians say that the Order of Operation was created out of a desperate need for simplified solutions. Our helpful Parentheses/Brackets Exponent Multiplication Division Addition and Subtraction had to have come from somewhere right? While you’re at it, let’s talk a bit about how the Order of Operation which is known as PEMDAS (British version – BEDMAS) came to be. Think of this as a brain teaser, and while they may be a bit pesky sometimes, they are certainly interesting and great for improving your memory and processing abilities. If your answer is zero, four, seven, or a decimal fraction, you might want to take another go at it before taking a peek at the solution. However, the more contradicting the answers are, the more viral a question will go. It’s gotten to a point where they can’t decide what the correct answer is, but it’s actually a simple PEMDAS operation and the final answer is set in stone. More simply put, the answer depends on whether you were taught the BODMAS or the PEMDAS method at school.Still feeling confident right there? People online are coming up with a barrage of different answers. d324s8grlA- ?Moon-faced Assassin of Joy? July 30, 2019 It's either 1 or 16 depending on which mathematician you listen to, because order of operations isn't a hard and fast rule, and math is really just a language.Īnd nothing is true. So why is this happening? According to one Twitter user, the answer depends on which mathematician you listen to: It's 16 and if you say otherwise start packing your clown shoes ?- karla July 29, 2019 I have 2 math degrees it's 1- laur♏️ July 30, 2019 It is used to determine the likelihood t.

Tweeple can't seem to agree upon the correct answer.Īccording to PEMDAS you need to get rid of parathenses first soĨ/8=1 answer is one.- koook July 28, 2019 Answer (1 of 18): Top Five Formulas in Math 1.Arithmetic mean (average) sum of values divided by number of values. Were you able to solve the equation? Did your answer come down to either 16 or 1? Oomfies solve this /0RO5zTJjKk- em ♥︎ July 28, 2019 People can't agree on the correct answer. Since being shared online, it has gone viral with over 12,000 'likes' and thousands of comments. So why is this seemingly simple equation dividing the Internet? Posted by a Twitter user on Monday, 8 divided by 2(2+2) is the equation in question. At first glance it seems like school-level math. ![]()
