to do with my maths education at school. I was told three different answers by three math teachers at school.

Im wondering what answers you will suggest?

3 here as well. What other answer could three possibly be??

Glitterknickaz Wed 05-Jan-11 10:18:57

3, as you are stating the numbers between

I'd say 3 as well.

NorwegianMoon Wed 05-Jan-11 10:19:45

all wrong, 1 isnt a number?

id have thought 3 as well

mylifewithstrangers Wed 05-Jan-11 10:20:20

Well 3 or 5 are valid. Can't really find a justification for 4.

3 for the numbers between exclusive
5 for the numbers between inclusive

Without specifying exclusive or inclusive I'd say either answer is correct.

My instinct is 3 but "between 1 and 5" could mean 5-1=4.

1 isnt a number? hmm what is it then?

TheCoalitionNeedsYou Wed 05-Jan-11 10:21:49

mylifewithstrangers - Between is exclusive by default.

I this children's homework? I find there are a lot of ambiguously-worded questions in my DSs homework. Annoying

NorwegianMoon Wed 05-Jan-11 10:22:12

i was told:

3 (2,3,4)
4 (2,3,4,5) 1 isnt a number its a primary number (still a number in my mind)
5 (1,2,3,4,5)

This is why I dont have a maths GCSE and can barely subtract.

Sorry got me thinking from the stargazing thread about astronomy if I could have my time again

HowToLookGoodGlaikit Wed 05-Jan-11 10:23:15

I have a maths GCSE and I have never heard that 1 isnt a number shock

TheCoalitionNeedsYou Wed 05-Jan-11 10:23:17

Actually, you didn't specify that it's natural numbers only, so the answer is 'an infinite number of real numbers'.

sickoftheholidays Wed 05-Jan-11 10:23:53

there are an infinite number of numbers between 1 and 5, it just depends how many decimal places you want to go down to.
but I suspect that is a gcse/alevel maths answer. If you are 6 years old, the answer is 3. I think. maybe.

TheCoalitionNeedsYou Wed 05-Jan-11 10:26:37

1 is a number, so is squrt(2), so is pie, so is e, so is i, so is 1/3 and so is 0.12566664.

That is a prime, irrational, imaginary, real or whatever they are all still numbers.

1 isn't considered a prime number anyway.
