• 3. EXAMPLES• 4 + 8 = 12• -7 * 2 = -14• 10 / 2 = 5• -12 -4=-16
• 4. Operations with Integers Addition Subtraction Multiplication Division
• 5. Addition of Integers• When the signs of the numbers being added are the same, add their absolute values--The sign of the answer is the same as the sign of the numbers added together• When the signs of the numbers being added are different, subtract their absolute values--The sign of the answer is the same as the number with the largest absolute value
• 6. Subtraction of Integers• Add the opposite and refer to the addition rules (change the subtraction to addition and change the sign of the number being subtracted)
• 7. Multiplication of Integers• When the sign of the numbers being multiplied are the same, multiply the numbers--The sign of the answer is positive• When the sign of the numbers being multiplies are different, multiply the numbers--The sign of the answer is negative
• 8. Division of Integers Division involving two numbers with like (i.e. the same) signs always results in a positive answer.Division involving two numbers with unlike (i.e. different) signs always results in a negative answer.
• 9. SOLUTIONS FIND THE VALUES OF : -20 / -4 = 5 {- / - = +} 56 / 8 = 7 {+ / + = +} -42 / 7 = -6 {- / += - }
