  1. Warm up • How long does a car traveling at 70 mph take to travel 88 miles, in hours? • If you are buying kiwis for $1.89 per pound, how much will you pay for 20 ounces of kiwis?

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

  3. Definitions Identifying Parts

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

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

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

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

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

  9. Exponent • The number up in the air next to a base • The number of times you multiply something times itself • Examples: 3 12 4

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

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

  12. 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)

  13. ADDITION • Sum • Plus • Add • More Than • Increased

  14. SUBTRACTION • Difference • Minus • Decreased • Less Than (swaps the order)

  15. DIVISION • Quotient • Half • Divide by

  16. MULTIPLICATION • Product • Twice • Double • Triple

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

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

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

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

  21. Translate 8 + 3x Eight increased by three times x
