If it were all to be multiplied by zero it would have to look like this

(5 + 5 + 5 - 5 + 5 + 5 - 5 + 5) x 0

:worship:

I failed geometry in high school, and even i got this :idc:

Ben's reasoning makes sense.

Would also explain why Google assumed that 5*0 would be bracketed.

Benjamin 06-03-2012 11:52 AM

I would love to claim it's my reasoning, but it's the the order of operations. I learnt it when I was younger.

There's a bit about it on here (yes, I know it's wiki, but I cba searching the net for a better source):

Because of BODMAS, you do 5 x 0 first which is 0. Then add all of the other 5s together, then take away the rest of the fives. I just added the rest of the fives up wrong.

Ah BODMAS how could I forget

Josy 06-03-2012 12:51 PM

I would answer 40 for that :shrug:

Josy 06-03-2012 12:52 PM

WTF is BODMAS?

Smithy 06-03-2012 12:56 PM

Nicole is studying Maths at Uni if she says it's 0 then it's 0 :nono:

How on Earth did she answer this wrong then? The answer is 15.

Never even heard of BODMAS, and it just looks confusing :bored:

My nephew was doing his homework the other day too and was trying to explain to me that everything has to get rounded up to 100 now before you do sums or something like that.... pfft scrap that, just bloody add up what you see and thats that :shrug:

CharlieO 06-03-2012 01:03 PM

The answer is 15. Seriously people on here cannot do maths.

You always go a times/divide first and the add and subtract after unless there is brackets.

fp at people

How did you get 40?

CharlieO 06-03-2012 01:05 PM

I am cringing at everyone who got this wrong. It is such basic maths, no wonder they want to up the school leaving age to 18 and make maths A-Level compulsory.

MTVN 06-03-2012 01:06 PM

I'd say people still at school are most likely to get this right, I pretty much forgot most things about Maths when I dropped it

It's been a long time since I was at school Charlie, you tend to forget those type of rules unless you're a Maths teacher :laugh:

I added all the 5s together, but I have actually just noticed the - signs :laugh:

Marc 06-03-2012 01:08 PM

:laugh: I love how everybody is arguing over this equation.

I think there are good arguments for both 0 and 15.

Samuel. 06-03-2012 01:09 PM

Except the argument for 0 isn't right :p

The great thing about math is that there is only one right answer. This case 15

Marc 06-03-2012 01:18 PM

:laugh2: Josy

That's why I don't like Maths, there's no room for debate or interpretation

True I guess, I forget most of the stuff in a week so it's not surprising that 50 years (:tongue:) does that to you.
