00:00Welcome everyone. So yes, a lot of people thought that the answer for this question is supposed to be 16 because 8 minus 4 is 4.
00:07Here also 8 minus 4 is 4. There is no sign between this 4 and the bracket. So it means it is multiplication.
00:134 minus 4 multiplied by 4 answer is 16. This would have been fine if this 8 minus 4 was also given in bracket.
00:20But since that is not given in the bracket, then in that case what we should do?
00:24See, it is very important to realize that while solving these sums, you need to follow the rules of bond mass or FEMDES.
00:37Now in both the cases, it is very important to realize that division and multiplication come before addition and subtraction.
00:49And first thing, the highest precedence is given to brackets or parentheses.
00:53So first step would have been, we will keep 8 minus 4 as it is.
00:57And then we will do the brackets. So which is what? 8 minus 4 which is 4.
01:01Now here since there is no sign between 4 and the bracket, so it means multiplication.
01:06Now at this point realize that division and multiplication should be done before addition and subtraction.
01:13So we will keep 8 as it is.
01:15Minus 4 multiplied by 4 answer is minus 16.
01:18So now when you take 8 away from 16, the answer is what? 8.
01:27But now the sign will always be of the bigger number and 16 is the bigger between 2.
01:32And the sign with 16 is negative, so answer will be negative 8.
01:37I hope this is very very clear to everyone.
01:40That's it for today. I will see you in the next video.
