#1 is a polynomial of degree 2

Use the caret mark, (Shift-6, "^"), to indicate exponentiation.

1. x^2 + 2x + 2 means

2. (b^2c)/(d^4) means

3. 8xz + 1/2y means

In which case 3 is a polynomial of degree 2. (The degree of

in the first term is 1 and the degree of

in the first term is 1, but the degree of the term is the sum of the degrees of all of the variables in the term, so 1 + 1 = 2.)

But
8xz + 1/(2y) means

and this is NOT a polynomial.
