Degrees are a unit of angle measure. A full circle is divided into 360 degrees. For example, a right angle is 90 degrees. A degree has the symbol ° and so ninety degrees would written 90°. Another unit of angle measure is the radian.
The degree of a term is the exponent of the term. For example the term has a degree of 2.
If the term has more than one variable multiplied together it is the sum of the exponents. For example has a degree of 6 (4+2).
If there is no exponent, the degree is 1, since
If the term is just a constant its degree is zero. Recall that and so any constant (say 9) could be re-written:
The degree of a polynomial is the highest degree of any term in the polynomial. For example the polynomial has a degree of 5 because the x5 term has the highest degree. See ("degree of a term" above).
