The Know Zone program, Mathematics section, gets it all wrong and the presenters need to go to school first before they mislead children.

sample this,

21-3×2+4÷2=

These idiots are giving the answer as 20.

Shame on you Shame on you Shame on you Shame on you


the answer is correct as per how the question has been asked, note there is no mention of use bodmas that is why guys are coming up with conflicting answers

21-3x2+4/2

=(21)-(3x2)+(4/2)

=21-(6)+(2)

=15+2

=17

QED

@kenmac, does this make sense?

@faa, thats how some adults were taught after skipping lower primary. It looks like lower primary was unnecessary afterall. Why bother with primo if you are sure of doing Laplace Transform at some point?

Hahahaha...Let me try:

21-3×2+4÷2=
BODMAS Applies...so we start with Division=4/2=2
That gives us 21-3*2+2
Again BODMAS comes in---3*2=6
That gives us 21-6+2
Again BODMAS----leads to 21-8
Finally answer comes to 13.

So how answer is 13.....
