There are two places "degree' is used in math: In geometry, it is 1/360 of a complete rotation (circle) In algebra, it refers to the number of variables that are multiplied together in a term: In x3 [=(x)(x)(x)], the degree is 3. In x2y4, the degree is 6. in xy (=x1y1) the degree is 2. In wxy6z2 the degree is 10. In 1 (=x0) the degree is 0.
