I Know I'm A Bit Of A Numpty

We're my education is concerned but when did 2+1x3= 5 ? Wouldn't it be 9.

[emmie]

it would, unless it's a trick question.......

[Jackdaw33]

No, 5 is correct. You must do any multiplication before addition.

[emmie]

why, did someone's homework not add up.

[wolf63]

It is: 2+ (1x3) = 5

[Jackdaw33]

In other words you must do 1 x 3 then add it to 2.

[hereIam]

Yes, where did you see this ?

[emmie]

ok, that's me done and dusted

[Jackdaw33]

If you want the answer 9 then you must write (2 + 1) x 3

[Jackdaw33]

Google BODMAS.

[ichkeria]

Strictly yes the answer is 5.
But it does depend
If you say aloud when totting things up:
Two plus one (3) times 3: nine.
A helpful soul who was not trying to do tricksy stuff on Facebook would write 2 + (1X3) = ... even though the brackets are not really needed

My two had maths exams today and they were trying to explain to me why it was 5 and not 9.

Even at 13 they are way over my head lol

I got them the higher level GCSE mathematics book as the teacher told me they would be taking the higher level next year (higher science, English, history and geography as well).

I want to know where they got their brains from. It must be their father (degree in engineering) rather than me.

[Old_Geezer]

1x3=3
2+3=5
Always has as far as I can recall.

[Prudie]

It's not really brains cassa but knowing the rules (BODMAS for example as suggested). I'm sure you are brainy in other ways anyway.

[Jackdaw33]

2 + 3 x 8 = 26, whereas (2 + 3) x 8 = 40.

[cassa333]

I like to think I have life skills way beyond my academic ability lol

My two think that because I can't help with their maths homework I am a numpty on everything.

That comes from a boy who, where I am obviously not, is quite gifted academically but wants to do sociology as an option so he can learn to debate why a particular game is better than another!!! I told him he doesn't need to do sociology. He just has to learn how to get the better of me in a discussion and he will have got it. He thinks it is easy but he has a lot of ground to catch up on lol lol

[kvalidir]

Yes it's bodmas, you don't do all maths in a linear way , you have to do the multiplication before the addition hence you get 5 :)

[cassa333]

BIDMAS

They have been googling it at a rate of knotts for me.

OH came home and when presented with the same equation, first asked if there were any brackets. Even he knows about it.

Thank goodness I don't actually need to use anything more difficult that add, subtract , divide and multiply one at a time.
