00:00Welcome everyone. So today we are going to understand why the answer for this question is not supposed to be 1.
00:06See we have 7 plus 3, then we have 2 and then we have divided by 2 and then we have 7 plus 3.
00:13So please understand in first when you have some things like this you need to follow the rule of word mass or PEMDES.
00:21Now in both the cases what happens is we multiply or we do the brackets first.
00:26So this becomes 10, this becomes 10. Now there is no sign between this bracket and 2.
00:32Here also the same situation is there. That means it is multiplied and this is also multiplied.
00:37So this becomes what 20 divided by 20. The answer is 1. No, that is not how these things work.
00:43Especially at this step you have to realize that in mathematics division and multiplication hold equal residence.
00:51So at this step you just have to go from left to right. Whatever operation happens first on your left hand side has to be done first.
00:58So 20 divided by 2 multiplied by 10. Now after this the first operation happens from your left hand side is supposed to be 20 divided by 2.
01:06Which is 10 multiplied by 10. So answer for this question is supposed to be 100.
01:12I hope this is very very clear to everyone.
01:15That's it for today. I will see you in the next video.
01:18I will see you in the next video.
