  • 1. Math, Session 2 TIU College Entrance Test Review
  • 2.
    • WHAT IS THE DISTANCE BETWEEN
    • ANY NUMBER X AND Y?
    • What is the distance between 15 and 0?
    • 15
    • What is the distance between 21 and 46?
        • 25
    • What is the distance between -8 and 0?
    • 8
    • What is the distance between -30 and 50?
    • 80
    • What is the distance between -12 and -5?
    • 7
  • 3.
    • | 9 | =
    • | -4 | =
    • Absolute value is the same number, in positive form.
    • What is the distance between 15 and 0?
    • Is it | 15 – 0| or | 0 – 15| ?
    9 4
  • 4.
    • What is the distance between -8 and 0?
    • Answer: | -8 -0 | or | 0 - -8 |
    Distance = | X – Y | = | Y – X |
  • 5. Rule for addition of signed numbers of the same sign : Add the numbers and prefix the common sign. Rule for addition of signed numbers of different signs : Subtract the numbers and prefix the Sign of the number with the larger value.
  • 6. Rule for subtraction of signed numbers: Change the operation to addition, and change The sign of the second number. Then perform as in addition of signed numbers.
  • 7. Rule for two numbers with the same sign : The product/quotient of the two will be positive .
  • 8.
    • The rule for two numbers of different signs :
    • The product/quotient of the two will be negative .
  • 9. 1.) Solve by disregarding signs. 2.) Do cancellation when possible. 3.) Count the negative signs. If even  result is positive If odd  result is negative
  • 10. In general, Therefore, 5! =?
  • 11.
    • Math, Session 2, Algebra
  • 12.
    • Evaluate the following expression for x = 4:
  • 13.
    • We can only add or subtract like terms .
    Is the answer 11 x –w also correct? YES!
  • 14.
    • We can only add/subtract like terms .
    The simplified form of the AE above is:
  • 15.
    • We use the laws of exponents.
    • Some examples:
  • 16.  
  • 17.
    • Master multiplication of simple terms
    • 3 techniques to multiply (x+a)(x+b)
      • Distributive Property of Multiplication over Addition
      • F-O-I-L Method
      • Column Format
  • 18.
    • Technique 1: DPMA
  • 19. First Outer Inner Last
  • 20.  
  • 21.
    • You can use DPMA and the Column Format to multiply not only binomials, but also trinomials and AE’s with many terms.
  • 22.
