Integers

  1. 1. IntegersMADE BY - ASHI DHINGRACLASS VII - B
  2. 2. Integers• The set of whole numbers and their opposites
  3. 3. EXAMPLES• 4 + 8 = 12• -7 * 2 = -14• 10 / 2 = 5• -12 -4=-16
  4. 4. Operations with Integers Addition Subtraction Multiplication Division
  5. 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. 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. 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. 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. 9. SOLUTIONS FIND THE VALUES OF : -20 / -4 = 5 {- / - = +} 56 / 8 = 7 {+ / + = +} -42 / 7 = -6 {- / += - }
