what is the value of 3 in 13? any help greatly appreciated, thanks, Maths was never my strong point and nobody I have asked seems to know the answer either! Thanks again in advance.
Jupiter7 You should then ask what is value of 3 in 31 or even 311. The value of 3 changes with its position.
In the case, of 31 it represents 3 tens ... in the second case, it represents 3 hundreds.
I think that you KNOW these answers - you just don't understand the question! That's modern maths for you!
