How much money is karate?
It depends on the style and the school. Some have outrageous fees of over $100 a month, and testing fees as high as $1,500 for black belt. Others are very reasonable, my classes would cost you $40 a month and total testing fees to black belt (belts included) would be less than $450.
Karate is used in math by measuring. Karate measures the length of each stance, and the degrees of each kick and turn. it uses length, height, degrees and distance.

They all incorporate aspects of the original styles from Okinawa, and incorporate local martial arts as well.
