0, 1, 2, 3, 4, 5, 6, 7, 8, and 9 are the ten numbers that make up every other number! One is usually regarded as being the very first number on the number scale and it is the first number that babies are taught. One is symbolic of terms like “single” and “solo.” Likewise, “mono” can mean that there is only one of something. For example, a monorail is a railway where the track consists of a single rail, a monocle is an eyeglass with only one lens and monochrome means using only one color, such as is seen in black-and-white photographs.

There is only one of lots of things. There is only one planet Earth, there is only one Atlantic Ocean and there is only one you. All of these are unique. The number one is also synonymous with certain stories and legends. For example, the mythical creature known as a “cyclops” is described as being a giant with one huge eye in the center of its head.

One can represent the lowest number or the bottom of the lists. For instance, on a chart from 1-10 one is considered to be the lowest and worst rating. Hence, the number one can be associated with negative reviews.
