**Like terms:** The terms having the same literal (variable) with same exponents are called **Like** terms.

**Example: **

- 48x and -8x
- 5x
^{2}and ½ x^{2}

**Unlike terms: **The terms having the same variable with different exponents or different variable with same exponents are called Unlike terms .

**Example: **

- 8x and 3y
- 6x
^{2}and 3y^{2}

**The degree:**

The degree is the value of the greatest exponent of any expression. To find the degree we have to find the largest exponent in the polynomial. Coefficients can be ignored when we are finding the degree.

**Demonstration:**

Determine the degree of the polynomial 4x^{2} + x + 42?

The value of the largest exponent the answer is 2 since the first term is squared. Remember coefficients have nothing at all do to with the degree.
