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!

Have just tried again and discovered that if I put in 40+40x0 and then press= then I get 40, to which I can then add 1 to get 41. But if I put the whole sum in at once I get 81 - on both portrait and landscape, which must be the way I did it the first time when it got it right.

This thread shows how many people only read the original post before posting.

It's 3.14!

From twitter.........

Ha! RT @Micky_Jay: @standupmaths 40+40x0+1=3.14. If you give me 40 apples + 40 apples x 0 apples +1 apple....I'm gunna make me some pie!!!

And yet, Dewe, 2.49 recurring is equal to 2.5

Which is brilliant but I'm not sure some people on this thread are ready for that if mere bidmas is messing with their minds :)

PacificDogwood you sound like my dh when my poor children are struggling with their homework.

He can stick Fibonacci numbers up his bum too :o

We were taught the same as LittleMissGreen, x.5 round up or down to the nearest even. So 2.5 rounds down to 2, 3.5 rounds up to 4.

Anything slightly under or over .5 then you round to the nearest whole.
.49 round down, .51 round up, regardless of even or odd.

10,000 something - 10,000 something = 10,000 something else.

Discuss.

when you round, you round up if it's below .5 and up if it's .5 or above.

so 2.4 rounds down to 2, and 2.5 rounds up to 5.

that's also a reason why it's very important never to round before your final answer.
eg:
give this answer to 1 decimal place
2.34+2.35+2.38+3.69+3.89=

if you round on each part, you get 14.5
but if you round at the end you get = 14.65 = 14.7

Look in here under 'Tie-breaking' if you really want to do your head in understand the whys and wherefores of rounding (hint - if you thought the answer to the OP was 1 you might not want to go her )

I was taught this: 'The rule is, if the next digit is: 5 or more, we 'round up'. 4 or less, it stays as it is.' (copied from GCSE BiteSize, so what I'd expect our kids to be learning). And in over quarter a century of scientific algorithm development I've never seen anything else used.

I haven't read the whole thing, so don't know if I'm the first to say "Divorce Him". Seriously, if my DH tried to pull shit like that he'd be on a warning. But to be fair my degree is in symbolic logic (aka Brackets).

I always see anything with a / or a x as a complete sentence.

so 40 + 40 x 0 + 1 looks like 40 + 40x0 + 1 to me.

so 2.4 rounds down to 2, and 2.5 rounds up to 5

Umm: so 2.4 rounds down to 2, and 2.5 rounds up to 3

Dilys - I'm sure he knows better than to court the wrath of a Militant Logician!

nickel - or a clause, would that be correct grammatical analogy?

Grimma - 75

shurrup Grimma

choccy - yo ucan shurrup too.
I'm a bad typist.

it's 1

anything times 0 is 0.

0 plus one is 1

you're forgetting the first 40+ though!

pirate - read the thread.... the x0 only applies to the second 40

I dunno whether to laugh or cry.

lol, i read the thread. i LEARNT something today hurrah,

it's 41 !
