[00:00:00]Hey guys, welcome to this video. In this video, we want to find the value of this expression. 8 / 8 / 8 and again divided by 8.

[00:00:11]Are you ready to solve? Let's go ahead and get this started.

[00:00:15]8 / 8 gives us 1.

[00:00:20]And again here we have 8 / 8.

[00:00:25]So 1 / 1 is just 1.

[00:00:31]But this answer is not correct. Because according to the order of operations, when we have more than one division in an expression, we have to work from left to right. So here, first we have to do this division, then this division, and then finally this division. If we do this division before this division, it is wrong.

[00:00:59]So first we have to do this division. 8 / 8 = 1.

[00:01:06]So we have 1 / 8 and again divided by 8.

[00:01:14]Now we have to do this division. 1 / 8 can be written as 1 over 8.

[00:01:23]Then divided by 8.

[00:01:27]Now according to the KCF rule, K stands for keep, C stands for change, and F stands for flip.

[00:01:35]We can write keep the first fraction, change division to multiplication, and flip the second fraction.

[00:01:46]So we have 1 over 8 * 1 over 8. And this is equal to 1 * 1 gives us 1. So 1 over 8 * 8 = 64.

[00:02:00]So, we have 1 over 64.

[00:02:03]And this is our final answer to this problem.

[00:02:07]>> [snorts] >> The correct answer is 1 over 64.
