[00:00:00]Hi friends, welcome to Turbo Math Channel.

[00:00:03]In this video, we are going to solve three questions about PEMDAS rule.

[00:00:08]In the first question, we have 21 + 30 over 5 * 2 to the power of 2 - 12 / 4.

[00:00:17]What is the answer of this question? Can you solve it? We have addition, multiplication, exponent, subtraction, and division.

[00:00:26]To solve this question, we need to follow the order of operations, which is PEMDAS.

[00:00:32]PEMDAS shows the priority of the mathematical operations.

[00:00:35]If you don't pay attention to the PEMDAS rule, you get the wrong answer.

[00:00:40]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.

[00:00:58]Multiplication and division have the same level of priority, also addition and subtraction have the same level of priority.

[00:01:05]When we have both in an expression, we start from the left and simplify the question.

[00:01:10]Okay, guys.

[00:01:11]According to the PEMDAS rule, in this question, first we simplify this exponent.

[00:01:17]2 to the power of 2 equals 4.

[00:01:20]Now, the question is 21 + 30 over 5 * 4 - 12 / 4.

[00:01:28]Okay, guys. Now, we have addition, division, multiplication, subtraction, and another division. In this step, we simplify this division.

[00:01:37]30 / 5 equals 6.

[00:01:41]Now, we have 21 + 6 * 4 - 12, then / 4.

[00:01:49]In this step, we have addition, multiplication, subtraction, and division.

[00:01:54]According to the PEMDAS rule, in this step, we simplify this multiplication.

[00:02:00]6 * 4 equals 24.

[00:02:04]Now, we have 21 + 24 - 12, then / 4.

[00:02:10]We have addition, subtraction, and division. According to the PEMDAS rule, first we simplify this division.

[00:02:18]-12 / 4 equals -3.

[00:02:23]Now, we have 21 + 24, then -3. 21 + 24 equals 45. Now, we have 45 - 3.

[00:02:36]45 - 3 equals 42.

[00:02:40]The final answer of this question equals 42. Guys, if you want to get the right answer of this question, you must follow the PEMDAS rule.

[00:02:50]If you don't pay attention to the PEMDAS rule, you get the wrong answer. Okay, guys. Let's solve another question about PEMDAS rule.

[00:03:00]-1 * (14 - 28 / 4 * 3).

[00:03:08]What is the answer of this question? Can you solve it? We have multiplication, parentheses, subtraction, and division.

[00:03:17]Again, to solve this question, we need to follow the order of operations, which is PEMDAS.

[00:03:23]PEMDAS shows the priority of the mathematical operations, and if you don't pay attention to the PEMDAS rule, you get the wrong answer.

[00:03:30]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.

[00:03:45]As you know, multiplication and division have the same level of priority, also addition and subtraction have the same level of priority, and when we have both in an expression, we start from the left and simplify the question.

[00:03:57]Okay, guys.

[00:03:59]According to the PEMDAS rule, first we simplify this parentheses. Inside this parentheses, we have subtraction, division, and multiplication.

[00:04:07]First, we simplify this division. -28 / 4 equals -7.

[00:04:14]Now, we have 14 - 7 * 3 inside this parentheses, and the question is -1 * (14 - 7 * 3).

[00:04:26]Okay, guys. We have multiplication, subtraction, and parentheses. Again, we simplify the parentheses. Inside this parentheses, we have subtraction and multiplication.

[00:04:37]According to the PEMDAS rule, multiplication has higher priority than subtraction. So, first we simplify this multiplication.

[00:04:46]-7 * 3 equals -21.

[00:04:50]Now, we have 14 - 21 inside this parentheses, and the question is -1 * (14 - 21).

[00:04:59]14 - 21 equals -7.

[00:05:03]Now, the question is -1 * -7.

[00:05:08]-1 * -7 equals 7.

[00:05:13]The final answer of this question equals 7.

[00:05:16]Okay, guys. Let's solve another question about PEMDAS rule.

[00:05:22](5/8)^2 * (5 + 1/6).

[00:05:29]What is the answer of this question? Can you solve it? We have exponent, multiplication, parentheses, and addition.

[00:05:38]To solve this question, again, we need to follow the order of operations, which is PEMDAS.

[00:05:44]PEMDAS shows the priority of the mathematical operations, and if you don't pay attention to the PEMDAS rule, you get the wrong answer.

[00:05:52]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.

[00:06:09]Multiplication and division have the same level of priority, also addition and subtraction have the same level of priority, and when we have both in an expression, we start from the left and simplify the question.

[00:06:23]Okay, guys.

[00:06:24]According to the PEMDAS rule, first we simplify the parentheses. Inside this parentheses, we have 5 + 1/6.

[00:06:33]Since the denominator of this fraction is 6, we can write 5 as 30/6.

[00:06:39]Now, we have 30/6 + 1/6 inside this parentheses.

[00:06:45]Okay, guys. Now, the question is (5/8)^2 * (30/6 + 1/6).

[00:06:57]Again, we have exponent, multiplication, and parentheses.

[00:07:01]According to the PEMDAS rule, in this step, we simplify this parentheses.

[00:07:06]We have 30/6 + 1/6.

[00:07:09]30/6 + 1/6 equals 31/6.

[00:07:14]Now, the question is (5/8)^2 * 31/6.

[00:07:21]We have exponent and multiplication.

[00:07:24]According to the PEMDAS rule, first we simplify this exponent. We have (5/8)^2.

[00:07:32](5/8)^2 25/64.

[00:07:38]Now, we have 25/64 * 31/6.

[00:07:44]Okay, guys. 25 * 31 equals 775.

[00:07:52]And 64 * 6 equals 384.

[00:08:00]The final answer of this question equals 775/384.
