Warm Up

1. Define like terms in your own words.
   Like terms are terms with the same base raised to the same power.

2. Explain the difference between whole numbers and integers.
   Whole numbers are the set {0, 1, 2, …}. Integers are {…, –2, –1, 0, 1, 2, …}

Note

You know from Algebra 1: Principles of Secondary Mathematics that whole numbers (𝕎) and integers (ℤ) are both part of the set of Real Numbers (ℝ).
