It's a simple "glitch" in our decimal representation of fractions.

A cool example is 1/7 = .(142857)

6/7 = .(857142)

1/7 + 6/7 = .(142857) + .(857142)

7/7 = .(9)

You round off 1/7 to .142857, and 6/7 to .857142, and then add them together a don't get exactly 1 and you call it a "glitch" in the decimal representation of fractions?

When I open my Windows calculator and enter 1 divided by 7 and click the equal sign I get an answer. I store that answer in memory. I then enter 6 divided by 7 and click the equal sign and get an answer. I press the plus sign, and then press memory recall, and finally the equal sign, and it adds the two together and the answer is.......1!
