[00:00:00]If we have the expression 4s squared minus open parentheses 20 / 5 * 2 close parentheses and / 2s squared, then what is the correct answer of this question?

[00:00:14]Many people when solving this question first go for the exponent, which is 4s squared. And instead of this expression, they write 16 minus open parentheses 20 / 5 * 2 close parentheses / 2s squared.

[00:00:34]And [snorts] the next step, they go for the expression inside the parentheses and they start with the division between 20 and 5.

[00:00:41]So, instead of this expression, they write 16 minus open parentheses 4 * 2 close parentheses / 2s squared.

[00:00:54]Then, they go for the multiplication between 4 and 2 and they write this expression as 16 minus 8 / 2s squared.

[00:01:05]Next, they go for the subtraction between 16 and 8 and instead of this expression, they write 8 / 2s squared.

[00:01:15]And the final step, they go for the exponent and they write this expression as 8 / 4, which finally gives them the answer 2.

[00:01:25]However, this answer is absolutely wrong.

[00:01:29]Also, some other people when solving this question first go for the expression inside the parentheses and they start with the multiplication between 5 and 2 because they think multiplication has priority over division.

[00:01:43]So, instead of this expression, they write 4s squared minus open parentheses 20 / 10 close parentheses then / 2s squared.

[00:01:57]And the next step, they go for the division between 20 and 10. And instead of this expression, they write 4s squared - 2 / 2s squared.

[00:02:10]Then, they go for the exponents. And instead of this expression, they write 16 - 2 / 4.

[00:02:20]In the final step, they go for the division between 2 and 4 because they think division has a higher priority than subtraction.

[00:02:29]So, instead of this expression, they write 16 - 0.5, which finally gives them the answer 15.5.

[00:02:40]However, this answer is actually incorrect.

[00:02:44]All right. Now, let me show you how to solve this expression properly.

[00:02:49]To solve this question, we must follow a rule that is called PEMDAS.

[00:02:53]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.

[00:03:07]As you can see on the screen, in this expression, first we have an exponent, then a subtraction sign, followed by parentheses, then a division, and finally another exponent.

[00:03:21]According to the PEMDAS rule, first we go for the expression inside the parentheses because parentheses have the highest priority than the other operations.

[00:03:30]And inside the parentheses, first we have a division sign and then a multiplication sign.

[00:03:36]It's very important to note that multiplication and division are at the same level of precedence, and we must perform these two operations from left to right.

[00:03:46]So, first we go for the division between 20 and 5. And instead of this expression, we can write 4 s squared minus open parentheses 4 times 2 close parentheses then divided by 2 s squared.

[00:04:02]In the next step, we go for the multiplication between 4 and 2 and write this equation as 4 s squared minus 8 divided by 2 s squared.

[00:04:15]Then, we go for the exponents because after parentheses, exponent has the highest priority than the other operations. So, instead of this equation, we can write 16 minus 8 divided by 4.

[00:04:31]In the final step, we go for the division between 8 and 4 because according to the PEMDAS rule, division has a higher priority than subtraction.

[00:04:42]So, we write this equation as 16 minus 2 which finally gives us the answer 14.

[00:04:50]All right. Now, let's solve another math question together.

[00:04:54]What is the value of the expression 5 minus 3 inside the parentheses plus 2 s squared multiplied by open parentheses 6 minus 1 close parentheses? Many people when solving this question go straight to the first parentheses and instead of this equation, they write 2 plus 2 to the power of 2 multiplied by open parentheses 6 minus 1 close parentheses.

[00:05:23]In the next step, they go for the exponent and instead of this equation, they write 2 plus 4 multiplied by open parentheses 6 minus 1 close parentheses.

[00:05:36]Then, they go for the addition between 2 and 4 and write this equation as 6 multiplied by open parentheses 6 minus 1 close parenthesis.

[00:05:48]In the final step, they go for the expression inside the parenthesis and instead of this expression, they write 6 multiplied by 5, which finally gives them the answer 30.

[00:06:00]But, that's definitely wrong.

[00:06:03]To solve this question, they must follow the order of operations a step-by-step from top to bottom.

[00:06:09]As you can see on this screen, in this equation, first we have parenthesis, then addition sign followed by an exponent, then a multiplication, and finally another parenthesis.

[00:06:23]According to the PEMDAS rule, first we go for the parenthesis because P or parenthesis have the highest priority than the other operations.

[00:06:33]So, we rewrite this equation as 2 plus 2 squared multiplied by 5.

[00:06:40]In the next step, we go for the exponent because in the PEMDAS rule, after parenthesis, exponent has a higher priority than the other operations.

[00:06:50]So, instead of this equation, we can write 2 plus 4 multiplied by 5.

[00:06:58]In the final step, we go for the multiplication between 4 and 5 because multiplication has a higher priority than addition.

[00:07:07]So, we rewrite this equation as 2 plus 20, which finally gives us the answer 22.

[00:07:15]Okay, let's solve the final math question together.

[00:07:19]What is the value of the expression 20 minus 9 multiplied by open parenthesis 5 minus 2 close parenthesis?

[00:07:28]Many people, when solving this question, first go for the subtraction between 20 and 9 and instead of this equation, they write 11 multiplied by open parenthesis 5 minus 2 close parentheses.

[00:07:44]In the next step, they go for the expression inside the parentheses. I would write this expression as 11 multiplied by three, which finally gives them the answer 33.

[00:07:56]However, this answer is absolutely wrong.

[00:08:00]To solve this question, we must follow a rule that is called PEMDAS, as you can see on the screen. In this expression, first we have a subtraction sign, then a multiplication sign, and finally parentheses.

[00:08:14]According to the PEMDAS rule, first we go for the expression inside the parentheses, because parentheses have the highest priority than the other operations.

[00:08:23]So, instead of this expression, we can write 20 minus nine multiplied by three.

[00:08:32]In the next step, we go for the multiplication between nine and three, because according to the PEMDAS rule, multiplication has the higher priority than subtraction.

[00:08:43]So, we write this expression as 20 minus 27, which finally gives us the answer -7.
