specifically:
"p = m + r" is wrong, unless 'm' goes into 'p' EXACTLY ONCE and then leaves a remainder. (for instance, if i want the remainder when i divide 200 by 6, i clearly can't write 200 = 6 + r; that will give an absolutely absurd remainder.)
still, you can use this method. here's the refinement:
in general, 'm' will divide into 'p' some integer number of times, say 'j', and leave a remainder.
therefore,
p = jm + r
2s = 2jk + r
2s - 2jk = r
then factor out the '2' and proceed as before.
your heart's in the right place, but this needs a little overhaul.navalpike wrote:P=m+r
2s=2k+r
2s-2k=r
2(s-k)=r
