Integers:{…2, 1, 0, 1, 2…}
Rational Numbers:Numbers that CAN be written as "fraction", "repeating decimals" or "terminating decimal" Ex: 5, 0, 4, $\frac{2}{5}$,5.67,4.$\overline{5}$
Irrational Numbers:Numbers that CANNOT be written as "fraction", "repeating decimals" or "terminating decimal" Ex:$\sqrt{5}$,$\pi$, 24.67934
