Remember:
- Standards A-SSE.A.1a, A-SSE.A.1b and N-RN.B.3: interpret parts of expressions and reason about sums and products of rational and irrational numbers.
- Terms are added; factors are multiplied; a coefficient is the number factor of a term.
- In \(P(1+r)^{n}\), the factor \(1+r\) multiplies the amount once per period.
- Rational plus irrational is irrational, and nonzero rational times irrational is irrational.
- Two irrational numbers can have a rational sum or product.
