Strange math!

Talk about anything that doesn't fit into the other catergories.

Strange math!

Postby DoomRater on Thu Feb 12, 2009 2:13 pm

Did I ever mention here how I once posed the question "1 minus .9 repeating equals... what?" to my math teacher? His answer was .1 repeating, hilariously enough, which I knew couldn't be the case. And for a long while I had thought the answer was something like 1/infinity until I found out the correct answer.

And to think all those calculators that displayed .9 repeating really DID display the correct answer.

Score!

Yeah, it was much easier to understand when I learned that a repeating decimal should be thought of as a process instead of a constant number. The problem lies in how the decimal system displays number, not in that actual value of its number.
