• 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.
