Across
  1. 3. -labeled I,II,III< and IV as shown
  2. 5. property -which can be used to find the product of a number and a sum or difference.
  3. 8. term -has a number part but no variable part such as 8 in the expression above.
  4. 11. inverse -the opposite of a is its additive inverse
  5. 12. numbers -is the set of all rational and irrational numbers as illustrated in the venn diagram below.
  6. 13. number -ia a number a/b where a and b are integers and =0
  7. 15. inverse -zero does not have a multiplicative inverse because there is no number such that o a = 1
  8. 18. square -as shown in example 1 the square root of a perfect square is an integers.
  9. 19. absolute value -for example 4 and -4 are opposite because they are both 4 units from 0 but are on opposite sides of 0.
  10. 20. -the number or expression inside a radical symbol is the radicand.
  11. 21. of change -compare a change in one quantity to change in another quantity
Down
  1. 1. identity -the identity property states that the product of a number a and 1 is a
  2. 2. square -an irrational number of two integers
  3. 4. statement -has a hypothesis and a conclusion.
  4. 6. -two lines in the same plane are parallel if they do not intersect
  5. 7. identity -the inverse property states that the sum of a number a and its opposite is 0
  6. 9. -of a nonvertical line is the ratio of the vertical change
  7. 10. coefficient -the number part of a term with a variable part is called coefficient of the term
  8. 14. terms -are terms that have the same variable part such as -x and 2x in the expression above.
  9. 16. -are numbers -3,-2,-1,1,2,3.
  10. 17. expressions -the equation 3(x+2)=3(X)+3(2).
