Pi is not equal to 22 sevenths.
Pi is irrational, which literally means "not
a ratio."
22 sevenths was Archimedes' upper bound for
pi.
By the way the greek letter is pronounced
"pî," not "pie."
One is not a prime number, it is a unit.
A prime number must have two factors.
Infinity is not a number.
Although numbers don't have to be finite,
there is no spot on the number line where
there is "infinity".
Subtraction and Division do not come after
Multiplication and Addition in the order of
operations,
they go together.
They are the same operations, just inverses.
Zero to the zeroth power does not equal one,
it is undefined.
Whole numbers can not be negative,
but they do include zero.
Multiplying nothing does not equal nothing,
it equals one.
One is the multiplicative identity
just like zero is the additive identity.
