Across
  1. 4. a rule of correspondence connecting the elements of one set with the elements of another set such that each member of the domain corresponds to a unique member of the range.
  2. 5. depends on or varies with the value of another variable
  3. 8. a statement that one expression is greater than (or less than) the other.
  4. 9. a hierarchy for performing operations
  5. 11. polynomial, in which the highest power of one variable is 2 or less.
  6. 13. quantities that do not vary, also called the missing element
  7. 14. a symbolic statement and can be either an arithmetic expression, or an algebraic expression.
  8. 15. a single term
  9. 16. theory and practice of arithmetic operations that uses symbols, especially letters, to represent unknown variables in equations
  10. 18. a symbol for an element from a specified replacement set
  11. 19. the result of binomial linear expressions that involve x to the second power, also known as “x squared.”
  12. 20. an ordered set of numbers such that there is a first term, a second term, a third term, and so on. The Formulas algebraic expressions that contain more than one variable
Down
  1. 1. Equations that contain only numbers
  2. 2. a popular way of introducing functions. Something is fed into the machine (the “input”) and operated on by a rule, and the resulting output comes out of the machine.
  3. 3. a single term whose variables, as well as the powers of each variable, correspond.
  4. 6. two-term polynomials with a highest power of 1, such as (2x + 1) or (3x - 7), can be used to demonstrate multiplication in an array
  5. 7. either a number, a variable, or a product or quotient that includes one or more variables.
  6. 10. patterns that grow or change
  7. 12. two complete repetitions of the repeating pattern segment, or, in other words, the shortest string of elements that repeats in a pattern.
  8. 17. a statement that two expressions are equal
