This Math Trick Will Blow Your Mind!

[00:00:00]Hey guys, welcome to our channel. We want to find the value of this expression. Here we have 1 - 3 * 1 - 3 in parentheses.

[00:00:09]What is the answer of this question? Can you solve it correctly? Most people when solving this math expression, at first they go for this subtraction between 1 and 3 and write instead of this expression -2. Then they go for this for this parentheses and write instead of this expression -2 again.

[00:00:30]Finally, they go for this multiplication between -2 and -2 and write instead of this expression 4.

[00:00:38]But this answer is not correct because according to the order of operations, which is PEMDAS, we have to solve this math expression in this way. First, parentheses, then exponent, then [snorts] multiplication or division, and then addition or subtraction. Remember that multiplication and division have the same level of priority, and addition and subtraction have the same level of priority, too.

[00:01:03]Now, first, we have one multiplication here because when a number is placed next to parentheses, it means multiplication, and usually we don't write this multiplication for brevity.

[00:01:16]Now, first, we have one parentheses that we have to solve it first. If we do this multiplication and this subtraction first, it is wrong.

[00:01:26]1 - 3 gives us -2. Let's rewrite this expression. We have 1 3 * -2 in parentheses.

[00:01:37]>> [snorts] >> In next step, we have one subtraction here and one multiplication here, and as we know, multiplication has higher priority than subtraction.

[00:01:48]So, we have to work we have to solve this multiplication first.

[00:01:55]So, 3 * -2 = -6.

[00:02:00]Finally, we have 1 - -6.

[00:02:06]Negative * negative = positive.

[00:02:11]Now, 1 + 6 gives us 7.

[00:02:16]So, our final answer to this question is 7.
