🔥Can You Solve This TRICKY PEMDAS Puzzle?🤯Added:
Hi friends, welcome to turbomath's channel. In this video we are going to solve three questions about PEMDAS rule.
In the first question we have 270 minus 270 times five then over open parentheses 24 minus 21 close parentheses then all of them to the power of two.
What is the answer of this question? Can you solve it? We have subtraction, multiplication, division, parentheses, and exponent.
To solve this question we need to follow the order of operations which is PEMDAS.
PEMDAS shows the priority of the mathematical operations and if you don't pay attention to the PEMDAS rule, you get the wrong answer.
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.
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, let's simplify and solve this question step-by-step together.
We have 270 minus 270 times five then divided by open parentheses 24 minus 21 close parentheses then all of them to the power of two.
Okay guys, first we simplify these parentheses. Inside these parentheses we have subtraction and multiplication.
According to the PEMDAS rule, multiplication has higher priority than subtraction. So, first we simplify this multiplication. Negative 270 times five equals negative 1,350.
Now we have 270 minus 1,350.
270 minus 1,350 = -1,080.
Okay, guys. Now we have -1,080 / ( 24 - 21) and all of them to the power of two. In this step, we simplify this parentheses. 24 - 21 = 3.
In this step, we simplify this parentheses. 24 - 21 = 3. Now we have -1,080 / 3 to the power of two.
Okay, guys.
3 to the power of two = 9. Now we have -1,080 -1,080 / 9 = -120.
The final answer of this question = -120.
Okay, guys. Let's solve another question about PEMDAS rule.
2 to the power of two - ( 89 / 2 * 4) * 4.
What is the answer of this question?
Again, to solve this question, we need to follow the order of operations, which is PEMDAS.
PEMDAS shows the priority of the mathematical operations, and if you don't pay attention to the PEMDAS rule, you get the wrong answer. In this 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.
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. According to the PEMDAS rule, first we simplify this parentheses. Inside this parentheses, we have division and multiplication.
Because division and multiplication have the same level of priority, we start from the left and simplify the question.
89 / 2 = 44.5.
Now, we have 44.5 then * 4.
Okay, guys.
Now, the question is 2 ^ 2 - ( 44.5 * 4) then * 4.
Again, we simplify this parentheses.
44.5 * 4 = 178.
Now, we have 2 ^ 2 - 178 then * 4.
We have exponents, subtraction, and multiplication.
In this step, according to the PEMDAS rule, first, we simplify this exponent.
2 ^ 2 = 4.
Now, the question is 4 - 178 then * 4.
We have subtraction and multiplication.
According to the PEMDAS rule, multiplication has higher priority than subtraction. So, first, we simplify this multiplication.
-178 * 4 = -712.
Now, we have 4 - 712.
4 - 712 = -708.
The final answer of this question = -708.
Okay, guys. Let's solve another question about PEMDAS rule.
5/6 ^ 2 * ( close parentheses.
What is the answer of this question? Can you solve it? We have exponent, multiplication, parentheses, and addition.
To solve this question, again, we need to follow the PEMDAS rule.
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.
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.
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.
According to the PEMDAS rule, first, we simplify these parentheses. We have 8 + 1/3.
Since the denominator of this fraction is 3, we can write 8 as 24/3.
Now, we have 24/3 + 1/3 inside these parentheses.
Okay, guys.
24/3 + 1/3 = 25/3.
Now, the question is 5/6 ^ 2 * 25/3.
5/6 ^ 2 = 25/36.
Now, we have 25/36 * 25/3.
Okay, guys. 25 * 25 = 625.
And 36 * 3 = 108.
The final answer of this question = 625/108.
Guys, if you want to get the right answer of this question, you must follow the PEMDAS rule.
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.
