[00:00:00]Hi friends, welcome to Turbo Math Channel. In this video, we are going to solve three questions about PEMDAS rule.

[00:00:07]In the first question, we have -8 * (7 - 14 / 2 * 3).

[00:00:16]What is the answer of this question? In this question, we have multiplication, parentheses, subtraction, and division.

[00:00:23]To solve this question, we need to follow the order of operations, which is PEMDAS.

[00:00:29]PEMDAS shows the priority of the mathematical operations, and if you want to get the right answer of this question, you must follow the PEMDAS rule.

[00:00:37]In the PEMDAS 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.

[00:00:54]Multiplication and division have the same level of priority. Also, addition and subtraction have the same level of priority. When we have both in an expression, we start from the left and simplify the question.

[00:01:05]Okay, guys.

[00:01:06]According to the PEMDAS rule, first we simplify this parentheses. Inside this parentheses, we have subtraction, division, and multiplication. First, we simplify this division. -14 / 2 = -7.

[00:01:20]Now, we have 7 - 7 * 3 inside this parentheses.

[00:01:25]The question is -8 * (7 - 7 * 3). Okay, guys. Again, we simplify this parentheses. Inside this parentheses, we have subtraction and multiplication.

[00:01:38]Multiplication has higher priority than subtraction. So, first, we simplify this multiplication.

[00:01:46]-7 * 3 = -21.

[00:01:50]Now, we have 7 - 21 inside this parentheses. The question is -8 * (7 - 21) Okay, guys.

[00:02:02]We have multiplication, parentheses, and subtraction. In this step, we simplify these parentheses. We have 7 - 21. 7 - 21 = -14.

[00:02:15]Now, we have -8 * -14.

[00:02:19]Okay, guys.

[00:02:21]-8 * -14 = 112.

[00:02:27]The final answer of this question = 112.

[00:02:31]Guys, if you want to get the right answer of this question, you must follow the PEMDAS rule.

[00:02:37]If you don't pay attention to the PEMDAS rule, you get the wrong answer. Let's solve another question about PEMDAS rule.

[00:02:46]9 ^ 2 - 2 * 11) * 11.

[00:02:54]What is the answer of this question?

[00:02:56]In this question, we have exponents, subtraction, parentheses, division, and multiplication.

[00:03:02]To solve this question, we need to follow the order of operations, which is PEMDAS.

[00:03:07]PEMDAS shows the priority of the mathematical operations, and if you want to get the right answer of this question, you must follow the PEMDAS rule.

[00:03:16]In the PEMDAS rule, P stands for parentheses, E stands for exponents, M stands for multiplication, D stands for division, A stands for addition, and S stands for subtraction.

[00:03:32]Multiplication and division have the same level of priority. Also, addition and subtraction have the same level of priority.

[00:03:38]When we have both in an expression, we start from the left and simplify the question.

[00:03:43]Okay, guys.

[00:03:44]According to the PEMDAS rule, first, we simplify these parentheses. Inside these parentheses, we have division and multiplication.

[00:03:51]Because multiplication and division have the same level of priority, we start from the left and simplify the question.

[00:03:57]118 / 2 = 59. Now we have 59 * 11 inside this parentheses. The question is 9 ^ 2 - (59 * 11) * 11. Okay, guys.

[00:04:16]We have exponents, subtraction, parentheses, and multiplication.

[00:04:20]Again, we simplify this parentheses.

[00:04:23]We have 59 * 11. 59 * 11 = 649.

[00:04:32]Now we have 9 ^ 2 - 649 * 11. Okay, guys. We have exponents, subtraction, and multiplication.

[00:04:43]In this step, according to the PEMDAS rule, first we simplify this exponent.

[00:04:48]9 ^ 2 = 81.

[00:04:52]Now we have 81 649 * 11.

[00:04:58]Now we have subtraction and multiplication. Multiplication has a higher priority than subtraction. So, first we simplify this multiplication.

[00:05:06]-649 * 11 = -7,139.

[00:05:16]Now we have 81 -7,139.

[00:05:22]Okay, guys. The final answer of this question = -7,058.

[00:05:30]Okay, guys. Let's solve another question about PEMDAS rule.

[00:05:35]8 / 2 * (2 / 1/2) + 3 ^ 2.

[00:05:44]What is the answer of this question? We have division, multiplication, parentheses, addition, and exponent.

[00:05:51]Again, to solve this question, we need to follow the order of operations, which is PEMDAS.

[00:05:57]PEMDAS shows the priority of the mathematical operations. If you want to get the right answer of this question, you must follow the PEMDAS rule.

[00:06:06]In the PEMDAS 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.

[00:06:20]Multiplication and division have the same level of priority. Also, addition and subtraction have the same level of priority. When we have both in an expression, we start from the left and simplify the question. Okay, guys.

[00:06:31]According to the PEMDAS rule, first we simplify this parentheses.

[00:06:35]2 / 1 / 2 To solve this part, we need to follow the KCF rule. In the KCF rule, K stands for keep, C stands for change, and F stands for flip.

[00:06:49]We keep the first number as it is, then we change the sign, and after that, we flip the second fraction. Now, we have 2 * 2 inside this parentheses. The question is 8 / 2 * (2 * 2) + 3 ^ 2.

[00:07:08]In this step, we simplify this parentheses.

[00:07:12]2 * 2 = 4. Now, the question is 8 / 2 * 4 + 3 ^ 2. Okay, guys. We have division, multiplication, addition, and exponent. In this step, we simplify this exponent.

[00:07:29]3 ^ 2 = 9.

[00:07:33]Now, we have 8 / 2 * 4 + 9.

[00:07:40]Okay, guys. We have division, multiplication, and addition. In this step, we simplify this division. 8 / 2 = 4.

[00:07:49]Now, we have 4 * 4 then plus 9.

[00:07:54]We have multiplication and addition.

[00:07:57]First, we simplify this multiplication.

[00:07:59]Okay, guys.

[00:08:01]4 * 4 = 16. Now, we have 16 + 9.

[00:08:07]16 + 9 = 25. The final answer of this question = 25.
