Prerequisites: Learners should know how to combine signed numbers.


  1. Read the information and examples for combining like terms.
  2. Using the first example, redo it on another piece of paper without looking at the answer. Then, check your work.

Key Questions (Critical Thinking Questions)

  1. Simplify: 2ab + 7ba (Apply the Commutative Property for Multiplication to get like terms)
  2. Give an example of a term that could be added to 4ab.
  3. 3x2 -4xy +8y2 + (? ? ?) = x2 -7xy +12y2
    4. 3a – 2ab + 4ac – 14b + ( ? ? ? ? ?) = -6ab - 8ac + 20b + 5c
    5. Give a real-life example as a model for combining like terms.
