[00:00:00]What is the value of the expression 3 s squared plus 60 divided by 3 multiplied by 5?

[00:00:08]Which option do you think is the correct answer to this question?

[00:00:12]At first glance, this expression seems very simple, but unfortunately, many people get tricked.

[00:00:20]Let's go step-by-step and solve it together.

[00:00:22]To solve this question, many people assume by calculating 3 s squared first, and instead of the original expression, they rewrite it as 9 + 60 divided by 3 multiplied by 5.

[00:00:36]In the next step, they usually perform the addition between 9 and 60 and simplify this equation to 69 divided by 3 multiplied by 5.

[00:00:47]Then, they proceed by doing the division between 69 and 3, which gives them 23 multiplied by 5.

[00:00:55]And finally, they multiply 23 by 5, which ends up with the answer 115.

[00:01:02]Then, without any hesitation, they quickly say that option D is the correct answer to this question.

[00:01:11]However, this answer is absolutely wrong.

[00:01:16]Also, some other people when solving this question first go for the expression 3 s squared, and they simplify it to 9 + 60 divided by 3 multiplied by 5.

[00:01:28]In the next step, they usually go for the multiplication between 3 and 5 because they think multiplication has priority over division.

[00:01:38]So, they rewrite this equation as 9 + 60 divided by 15.

[00:01:43]Next, they perform the division between 60 and 15 since they believe division has priority over addition.

[00:01:52]And they rewrite this equation as 9 + 4, which ultimately gives them the answer 13.

[00:01:59]And immediately, they conclude that option B is the correct answer to this question.

[00:02:06]However, it's not the correct answer to this question.

[00:02:11]All right. Now, let me show you how to solve this expression properly.

[00:02:15]To solve this question, we must follow the PEMDAS rule.

[00:02:19]We should perform these operations exactly in order from top to bottom, step by step.

[00:02:25]Okay. As you can see in the image, in this expression, first we have an exponent, then an addition sign, followed by a division, and finally a multiplication.

[00:02:37]We should have started with the exponent, because in this expression, exponent has a higher priority than the other operation.

[00:02:45]So, this expression simplifies to 9 + 60 / 3 * 5.

[00:02:52]In the next step, we need to handle the division and multiplication, since multiplication and division have higher priority than addition.

[00:03:01]However, it's really important to understand that multiplication and division have equal precedence.

[00:03:08]In this situation, the best thing to do is to start from the left side of the expression and move toward the right, performing division and multiplication in order.

[00:03:17]So, first we perform the division between 60 and three, and this expression simplifies to 9 + 20 * 5.

[00:03:27]In the final step, we do the multiplication between 20 and five, which gives us 9 + 100.

[00:03:35]And finally, the value of this expression is equal to 109.

[00:03:40]That's great. Option C is the correct answer to this question.

[00:03:46]All right. Now, let's solve another tricky math question together.

[00:03:50]What is the value of expression 56 / 4 multiplied by open parenthesis 7 + 7 closed parenthesis?

[00:04:00]Which option do you think is the correct answer to this question?

[00:04:04]Let's take a closer look and solve it together.

[00:04:07]In the first step, most people start by solving the expression inside the parenthesis and replace it with 56 / 4 multiplied by 14.

[00:04:18]In the next step, they go for the multiplication between 4 and 14 because they think multiplication has priority over division.

[00:04:27]So, [snorts] this equation simplifies to 56 / 56, which finally gives them the answer 1.

[00:04:34]And immediately, they conclude that option A is the correct answer to this question.

[00:04:42]However, that's definitely wrong.

[00:04:45]As you can see on the screen, in this expression, first we have a division sign followed by a multiplication sign, and finally parenthesis.

[00:04:55]To solve this question, we need to use the PEMDAS rule.

[00:04:59]PEMDAS shows us the priority of the order of operation.

[00:05:03]So, we start with the parenthesis first because it has the highest priority than the other operation.

[00:05:10]Okay, this equation simplifies to 56 / 4 multiplied by 14.

[00:05:17]Now, it's time to simplify this equation.

[00:05:20]It's very important to note that in the PEMDAS rule, multiplication and division have exactly the same level of priority.

[00:05:28]In this case, all we need to do is to start from the left of the expression and move a step by step toward the right.

[00:05:34]So, first we perform the division between 56 and 4, which simplifies this equation to 14 multiplied by 14.

[00:05:43]And finally, the value of this equation will be 196.
