    right

    and the degree is the highest exponent

    Is it 8?

    in a particular term for example 6pq has degree 2 2p5q = degree 6

    do I add up the degrees?

    No not 8 look at each variable and add up the exponents

    5q is only 1 degree

    because its q^1

    ignore the numbers before the variables

    So it would be eight because p^2=2 and q=1 and p^3=3 right?

    I miss counted I actually got nine.

    No - you don't add up the exponents in all the terms you find the term which has the highest count of exponents Thats the degree

    So 7p^3q

    for example the trinomial x^2y + y^2 + y has degree 3 because x^2 y has 2+1 = 3 exponents

    yes 7p^3 q has highest degree 4

    so in descending order its 7p^3q -10p^2q – 5q
