Question from Brendan, a student:

Let's say you have 291/2 and its between 281/2=14 and 301/2=15. My question is where do the
14 and the 15 come from or in other words how do you get those?

Hi Brendan,

29 is between 28 and 30 so half of 29 is between half of 28 and half of 30. Half of 28 s 14 and half of 30 is 15.
