Quoted wrong post!
Anyway, if your calculator gives an answer of 35, get a new calculator!

BODMAS
BODMAS
Not sure about school but I remember my Dad drumming this into me from a young age.
The answer is 23.
Cheers,

According to my casio fx-85GT Plus its 23,
my Sis who is a maths brainbox says you would never express 3+4x5, it should always have clarification such as brackets so doesn't deserve an
answer, 0 out of 10!
If in doubt I would apply bodmas.
According to usborne junior illustrated maths dictionary page 63 'many part calculations' Brackets, Others (such as powers), Division,
Multiplication, Addition, Subtraction therfore 4x5=20+3=23, your daughters teacher needs to go back to junior school and learn the stuff they're
teaching our 6 yr olds!
What hope do our kidsa have with teachers like that

The calculator on Windows works as a basic (non-BODMAS) calculator in basic mode and as a proper BODMAS one in scientific mode.
Now how about "3 4 5 * + ." ?

I think this goes to show that not everyone is mathematically (or arithmetically) minded. Nothing wrong with that but definitely worth being more
aware of. Just think how many mistakes must happen every day when fundamental arithmetic is so poorly understood by so many.
There is a really good cure for it - try working in a bar without one of those fancy touchscreen tills. I used to work in a pub part-time when at
university and you certainly get used to doing arithmetic in your head. I must say though, as a computer programmer, I do sometimes put in parentheses
when I know I probably don't need them. Then again when you have multi-variable expressions with a mix of boolean and arithmetic expressions and
perhaps a few method calls thrown in, it can get a bit more tricky...
I voted for 23 by the way
Think of it like this: If you are going to buy 5 cocktails and a pint of beer with cocktails at £4 and beer at £3. It would be 5 x £4 = £20 + £3 =
£23. You wouldn't expect to have to pay £35 which would be the price of 5 x (Beer + Cocktail) combos. In other words you would want 6 drinks in
total not 10 drinks.
I fancy a beer now...

I was always
taught to do the same, it saves alot of questions and mistakes
but 19 votes for 35 is a bit worring

There we go, the answer is "That's the wrong type of question"

Well whichever way you look at that multiplying anything by zero makes zero

Im really looking forward to my little girl growing up and asking me for help with homework, will give me a chance to relearn all the bits I was to
undisciplined to pick up when I was younger. The amount of things I look back on now and think - thats obvious, why on earth could I not pick that up
when I was 14?!

In an exam you would be expected to apply bodmas unless directed otherwise, such an ambiguous expression would not normally be used except to test
students knowledge of bodmas. Applying the rules of bodmas the result is always going to be 23.
If the expression was written (3+4)x5 then it would equal 35
As for 3 4 5 * + that would actually be 345 x + which it not strictly a recognised equasion.
