🔥 90% of People Get This WRONG! Maybe Even MrBeast! Can YOU?

[00:00:00]What is the value of the expression 200 / 2 * (1 + 4) * 2?

[00:00:12]Which option do you think is the correct answer to this question?

[00:00:15]This equation is so tricky that 90% of people get the wrong answer.

[00:00:21]Let's go step by step and solve it together.

[00:00:24]Many people when trying to solve this question, first go for the expression inside the parentheses because they believe parentheses have a higher priority than the other operation.

[00:00:35]So, they simplify this equation to 200 / 2 * 5 and again * 2.

[00:00:43]In the next step, they go for the two multiplication signs that I've highlighted in yellow because they think multiplication has a higher priority than division.

[00:00:53]So, instead of this equation, they write 200 / 20, which finally gives them the answer that 10.

[00:01:01]And immediately, they conclude that the correct answer to this question is option A.

[00:01:08]But, I have to say you were tricked and it's not the correct answer to this question.

[00:01:14]All right. Now, let me explain step by step how to solve this equation correctly.

[00:01:20]To solve this question, we must follow a rule that is called PEMDAS.

[00:01:24]In this rule, P stands for parentheses, E stands for exponent, M stands for multiplication, D stands for division, A stands for addition, and S stands for subtraction.

[00:01:38]We have to follow the order of operations I told you, step by step from top to bottom.

[00:01:44]Okay. In the first step, we go for the expression inside the parentheses because it has the highest priority among all the operations.

[00:01:54]So, instead of this equation, we can write 200 / 2 * 5 and again * 2.

[00:02:02]Okay, as you can see in the image, in this equation, we have one division sign followed by two multiplication signs.

[00:02:10]We must pay close attention that multiplication and division are at the same level of precedence.

[00:02:16]In this situation, the best thing to do is first start from the left and perform these two operations in order.

[00:02:23]So, first you perform the division between 200 and 2. We simplify this equation to 100 * 5 and again * 2.

[00:02:34]In the next step, we perform the multiplication between 100 and 5. And instead of this equation, we can write 500 * 2, which finally gives us the answer 1,000.

[00:02:47]That's great. Option D is the correct answer to this question.

[00:02:52]All right. Now, let's solve another tricky math question together.

[00:02:56]What is the value of the expression 84 / 12 * (8 - 1)? Close parenthesis.

[00:03:06]Which option do you think is the correct answer to this question?

[00:03:10]Let's take a closer look and solve it together.

[00:03:13]In the first step, most people will solve it by solving the expression inside the parenthesis and replace it with 84 / 12 * 7.

[00:03:23]In the next step, they go for the multiplication between 12 and 7 because they think multiplication has priority over division.

[00:03:33]So, this equation simplifies to 84 / 84, which finally gives them the answer 1.

[00:03:39]And immediately, they quickly say that option A is the correct answer to this question.

[00:03:47]However, it's not the correct answer to this question.

[00:03:51]As you can see on the screen, in this expression, first we have a division sign followed by a multiplication sign, and finally parentheses.

[00:04:01]To solve this question, we must follow a rule that is called PEMDAS.

[00:04:05]PEMDAS shows us the priority of the order of operation.

[00:04:09]So, we start with the parentheses first because it has the highest priority than the other operation.

[00:04:16]Okay, this equation simplifies to 84 / 12 * 7.

[00:04:22]Now, it's time to simplify this expression.

[00:04:25]It's very important to note that in the PEMDAS rule, multiplication and division have exactly the same level of priority.

[00:04:33]In this case, all we need to do is start off from the left of the expression and move a step by step toward the right.

[00:04:40]So, first we perform the division between 84 and 12. Let's simplify this equation to 7 * 7.

[00:04:48]And finally, the value of this equation will be 49.

[00:04:52]Therefore, option C is the correct answer to this question.
