Integers and Operation of Integers

This is about operation of Integers

1. Are positive and negative whole numbers.

2. Addition of Integers:

3. Addition of Integers: 20 + 10 30 -40 + -60 -100

4. Addition of Integers: -25 + 5 -3 + 7 -20 4

5. Subtraction of Integers:

6. Subtraction of Integers: - 3 4 - 7 + - ( ) - + 15 - 9 - + 24 + ( )

7. Multiplication of Integers: Rule 1: when multiplying integers with the same sign the product is positive. Rule 2 : when multiplying integers with different signs the product is negative.

8. Multiplying of Integers: - 2 6 × - 3 × -22 2 -44

9. Division of Integers: Rule 1: when dividing integers with the same sign the quotient is positive. Rule 2 : when dividing integers with different signs the quotient is negative. - ÷ - = + + ÷ + = + + ÷ - = - - ÷ + = -

10. Division of Integers: 12 -4 ÷ - 4 -3 ÷ ÷ -12 3 3 -30 -10

11. Get one half sheet of paper. Perform the indicated operation of integers. (-15) × (3) = (-6) × (-2) = (-4) ÷ (-4) = 96 ÷ (-16) = (-3) × (7) = (-4) + (-16) = 12 – 15 = 22 + (-22) = (-34) + 12 = (-17) – (-26) = -45 12 1 -6 -21 -20 -3 -22 9

12. Homework Write your answer in a one whole sheet of paper (intermediate pad). Please do a research about the following. What is fraction? What are the kinds of fractions? What are the classifications of fractions? What are the operations of fractions? Give at least five examples of fraction.
