- HSA-SSE.A.1 Interpret expressions that represent a quantity in terms of its context.
^{★}- Interpret parts of an expression, such as terms, factors, and coefficients.
- Interpret complicated expressions by viewing one or more of their parts as a single entity.
*For example, interpret P(1+r)*^{n}as the product of P and a factor not depending on P.

- HSA-SSE.A.2 Use the structure of an expression to identify ways to rewrite it.
*For example, see x*^{4}– y^{4}as (x^{2})^{2}– (y^{2})^{2}, thus recognizing it as a difference of squares that can be factored as (x^{2}– y^{2})(x^{2}+ y^{2}).

- HSA-SSE.B.3 Choose and produce an equivalent form of an expression to reveal and explain properties of the quantity represented by the expression.
^{★}- a. Factor a quadratic expression to reveal the zeros of the function it defines.
- b. Complete the square in a quadratic expression to reveal the maximum or minimum value of the function it defines.
- c. Use the properties of exponents to transform expressions for exponential functions.
*For example the expression 1.15*^{t}can be rewritten as (1.15^{1/12})^{12t}≈ 1.012^{12t}to reveal the approximate equivalent monthly interest rate if the annual rate is 15%.

- HSA-SSE.B.4 Derive the formula for the sum of a finite geometric series (when the common ratio is not 1), and use the formula to solve problems.
*For example, calculate mortgage payments.*^{★}
