- Distributive Property
We first stated the distributive property in Section 1.2, but in
Chapter 1 we did not have the symbolism of algebra, so we restate this
property in this section, using variables a, b, and c to represent
any given numbers:
a(b + c) = ab + ac.
- Similar Terms
If two or more terms are exactly the same except for their numerical coefficients,
we call them similar terms.
- Adding or Subtracting Variable Expressions
Use the distributive property and add similar terms.
