Common Error: Keep the Variable Part the Same
Common Error: Keep the Variable Part the Same is a Grade 7 math skill from enVision, Mathematics, Grade 7, covering Generate Equivalent Expressions. When adding like terms, add their coefficients. The variable part of the term does not change. Explanation When you combine like terms, you are only changing the coefficient, which tells you how many of that term you have. The variable part simply acts as a label and does not change. For example: Examples Correct: The variable part, , stays the same.
Key Concepts
When adding like terms, add their coefficients. The variable part of the term does not change.
