40+40x0+1 ?

[minimuffy]

40 + 40 x 0 + 1 =

A- 1
B- 41
c- 0

I say its B-41 as you need to multiply then add. (from what i remember of standard grade maths the acroymym BOMDAS- brackets off, multiply, divide, add, subtract)

DH says its 1.

please tell he's wrong!

While we're on this - have we covered nested brackets yet?

For instance 6 + (5 (4+3))2 -1

You are of course right, it's 15. about 300 000 people on FB have so far claimed it's 0.

Wooooooohoo- I got 75 there too

There's no way I'd have got that right yesterday.

I'm wondering whether we know the same people op, this was a huge discussion over a friends Facebook page last night!!

41

multiply 40X0 first, then add 40 + 0 +1 =41.

Ahhh so I was right on the questions thing on FB then punches fist in air surprised how many of my more intelligent friends weren't correct I have to say!

5 + 5 + 5 - 5 + 5 + 5 - 5 + 5 x 0 = 15

We learned BODMAS, O was for order.

Well done LeBOF.

Must admit I typed it in and then thought, bugger, the computer isn't going to work it out for me

Does anyone know when BODMAS came about, because I don't remember it from school when did o'level in 1979. A quick google seems to say that it came around with the invention of the calculator and the computer language. Although I can't find much to be honest. Handheld calculators were very new when I was at secondary, so could it be the older ones on this thread work things differently!

Originally thought answer was 1 but reading the whole of this thread i stand corrected. Just emailed the question to my work mates to see if they are thick or clever

First person to respond is just as crap as me so i dont feel so bad now

Havent read the thread, the answer should be one. Now going back to read the thread and see how it could be anything else.

i dont get the one with all the fives . My calculator says 0.

bruffin, I did o level in the 80s and we learned BODMAS then.

Bruffin - I don't remember the BODMAS acronym but I'm quite sure I learned the same rules of precedence at school (O -levels 77, A levels 79)

The rules have evolved over time, but the one at the nub of the OP is centuries old. Here is a bit of a discussion .

As to early calculators - well, the first was the Sinclair which used Reverse Polish notation and I really don't think we want to go there!

everyone in my office is thick too

41 - but it's a bad question because of the multiply by 0 bit

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

Pascha, BODMAS, there are no brackets and no order(powers/exponentials), no division.

The first operation is multiply. So multiply the last 5 X 0 = 0

Then add.
There are 5 +5s and 1 +0 = 25 + 0 = 25
Then take away the 2 -5s. 25-10 =15

Pascha - is your calculator the sort where you can type in that whole line at once or do you have to do it in stages? If the latter, its implicitly bracketing.
If the former - its a duff calculator!

I remember working out brackets first, but not the multiplication before addition and subtraction.

41 - but it's a bad question because of the multiply by 0 bit
Its a perfectly reasonable question. Its at the waaay simple end of the sort of thing anyone who writes software has to deal with all the time.

Now, if there was a divide by zero, that's a different matter.
