Number problem

[Matt_B]

This has been doing the rounds on Facebook recently (and probably originated a long time before) and has stirred up a lot of conversation. I thought I'd give it a go here. There is obviously only one answer but I'd be interested to see how many people remember how to work it out.

5 + 5 + 5 - 5 + 5 + 5 - 5 + 5 x 0 = ?

Edit: This is also my first ever poll, I think, so "yay" for that.

Yes, but I've never been an advocate of BODMAS so whenever you post the supposedly 'correct' answer it will obviously show that I am wrong!

How can you not be an advocate of basic mathematical principles?! It's not believing in division!

Years ago, people thought the earth was flat.

I''ve gone for 15, because that's the way I was taught maths. Things may have changed since then though!

Nope, you are correct.

I notice that there are no brackets involved it the issue.

There doesn't need to be. They are implied around the multiplication.

Told you I was crap at maths :icon_lol:

You're not (well, you may be, but in this case it's excusable). Most people see the x0 thing and realise that anything x0=0. They forget the correct order to do things though
