ANY positive number is greater than any negative number. Imagine you are digging a hole, and piling up the dirt you remove from the hole. The hole represents negative numbers- it goes lower than the surface. The piled up dirt represents positive numbers- it is higher than the surface. The surface is zero- neither positive or negative.

Positive numbers are greater than negative numbers. Decimals can be either positive or negative.
