00:00Welcome everyone. So today we are going to understand why the answer for this question is not supposed to be 1.
00:06We have 15 divided by 3 and then we have 10 divided by 2.
00:11Okay. So now at this point lot of people think that we will first do the brackets which is correct.
00:16The first step is absolutely correct to do the brackets that is 10 divided by 2 which is 5 and there is no sign between 3 and the bracket means it is multiplication.
00:24Now the goof up happens from this step because they think that you know this is so easy 15 divided by 3 multiplied by 5 is 15.
00:34So answer for this one is supposed to be 1.
00:36But that is not how things work in mathematics.
00:38You need to realize that division and multiplication hold equal precedence.
00:43So in sums like these you just go from left to right.
00:47Whatever operation happens first on your left hand side has to be done first.
00:50So 15 divided by 3 is 5 multiplied by 5.
00:55So answer for this question is supposed to be 25.
00:58I hope this is very very clear to FG1.
01:02That's it for today. I will see you in the next video.
