I made it 1, checked on my calc and that made it one also due to no brackets.

 

That's becuase the calculator isn't able to sort out operator precedence, you enter it linearly and it just performs the operations in the order you enter them.

 

You need a better calculator: http://www.wolframalpha.com/input/?i=40%2B40x0%2B1

 

...or, alternatively, to learn the limitations of the one you already have. Two wrongs don't make a right, and in this case the two wrongs are

a) you've not understood and taken into account the precedence of the mathematical operators, and
b) nor has your calculator.

Not that it makes the slightest difference, but my scientific calculator gets this one right, and so does even the iphone.

 

I would quote buy all my buttons seem to have gone lol.... (enter smiley here)

 

I was going to say 1.
I did fail A-level maths though. Twice.
(although the second time was because I didn't go to any lessons)

 

Blimey, you could be my double

 

In a primary school, give that to some young kids and see what they make of it

Only teach you basic maths at that level wouldn't criticise your 6 year old child for getting that wrong now would you

 

The correct answer:
40+40*0+1=41
However (40+40)*0+1=1
Been a long time since I left uni but even I find it easy!

 

Thought I'd see if the standard calculator on my HTC phone would get it right, and it does!

 

Very BODMAS

 

Got to be honest..that's how I was taught maths when I was at School.I didn't know that multiplication takes precedence over an addition.

So I just added up the sum as I saw it 40+40=80 x 0 =80 + 1 = 81.

Guess I'm crap at maths

 

problem there is 80x0 =0, not 80

the issue here is people presume brackets are involved, and they are not it seems

 

You make it sound like it's something to be proud of. It's not

 

I'd say 'crap' was an understatement myself
