[00:00:00]Hey guys and welcome to our channel. We want to find the value of this expression. We have here 9 - 3 * 2 + 8 / 4 in parenthesis in another parenthesis.

[00:00:15]What is the answer of this question? Can you solve it correctly? Most people when solving this math expression, first they go for this uh subtraction between 9 and three and write instead of this expression six. Then they go for this addition between eight and two and write instead of this expression 10. Finally they go for this uh division between 10 and four and write instead of this expression 2.5.

[00:00:43]And finally they go for this uh multiplication between 6 and 2.5 and write instead of this expression 15. But this answer is not correct because according to the order operations which is PAM does we have to solve this mass expression in this way. First parentheses then exponent then multiplication or division and then addition or subtraction.

[00:01:09]Remember that multiplication and division have the same level of priority and addition and subtraction have the same level of priority too. According to this rule in first step we have one parenthesis. Inside these parentheses, we have another parenthesis and addition. Now uh excuse me.

[00:01:33]Now we have to solve this parentheses inside uh big parenthesis.

[00:01:40]So 8 / 4 = 2. Finally we we have to solve this addition between 2 and two. And we can write inside of this expression four. Let's rewrite the expression. We have 9 minus 3. We have one multiplication here. Because when a number is placed next to parentheses, it means multiplication. And we usually don't write this multiplication for brevity times and four.

[00:02:11]In this step, we have one subtraction here and one multiplication here. And as we know according to the PEMDAS multiplication has higher priority than subtraction. So we have to solve this multiplication first. 3 * 4 = 12.

[00:02:28]Finally we have 9 - 12. So our final answer to this question is -3. Thank you for watching. Please like and subscribe if you like this
