every odd integer can be written as 4k+1 which I understand because you can break it down to 2(2k) + 1. But here is the part I don't get, every odd integer can also be written as 4k + 3 for an integer k.
It says this is true in the back of my book but I don't understand why?
Both of the above statements are false.Quote:
