Duh! Its invented (Score 1)

The act of counting is a human behavior. Counting relies on our ability to differentiate the units of stuff to be counted. Where does one unit begin and end? This is a human notion. Counting gives rise to mathematical operations and also allow us to conceptualize ways to measure the universe (volume, speed, groups and sets, angles, etc..) Math is a model for a human perception of reality and is therefore an invention.
