  3. Review HW

  4. EQ CCCA Unit 1 • Why is it important to understand the “language” of mathematics?

  5. Definitions Identifying Parts Guided NOTES

  6. Algebraic Expression • Can have variables, numbers, addition, subtraction, multiplication, division, parenthesis, square roots, exponents… • Examples:

  7. Variable • Symbols or letters used to represent an unknown • Examples: 

  8. Term • How many items are being added, subtracted, divided • Examples: 3 4

  9. Like Terms • Same variable raised to the same power • Examples:

  10. Coefficient • The number in front of a variable • Examples: 123 9 1

  11. Exponent • The number up in the air next to a base • The number of times you multiply something times itself • Examples: 3 1 4

  12. Base • What the exponent sits on • The part that has been raised to a power • Examples: 2 x y

  13. Constant • A number that has no variable • It can be positive or negative • Examples: -42 5 -8

  14. Factors • Items that are being multiplied together • Can be numbers, variables, parenthesis • Examples: 1 and 6…. Or 2 and 3 9 and x and y (x + 2) and (y – 3) 3 and (z – 9)

  15. Order of Operations • Simplify inside parenthesis • Take care of exponents • In order from left to right, multiplication or division • In order from left to right, addition or subtraction • Examples: -18

  16. Translations

  17. ADDITION • Sum • Plus • Add • More Than • Increased • Together

  18. SUBTRACTION • Difference • Minus • Decreased • Less Than (swaps the order) • Take away

  19. DIVISION • Quotient • Half • Divide by

  20. MULTIPLICATION • Product • Twice • Double • Triple • Times

  21. EXPONENTS • Square • Cubed • To the power of • Raised to a power

  22. Translate The sum of a number and 10 x + 10

  23. Translate The product of 9 and x squared 9x2

  24. Translate 9 less than g to the fourth power g4 – 9

  25. Translate 8 + 3x Eight increased by three times a number
