Addition of Integers

  1. 1. Grade 7 – Mathematics Quarter I ADDITION OF INTEGERS
  2. 2. •add integers using three different ways: colored counters, number line or rules.
  3. 3. Give the value of the following. 10 14 9 7 31. |3| = 2. |-10| = 3. |-14| = 4. |9|= 5. |-7| =
  4. 4. ADDITION OF INTEGERS 1. Colored Counters -+ 3 + 4 = = zero pair = 7 3 + (-4) = = -1
  5. 5. ADDITION OF INTEGERS Colored Counters -+ -6 + 4 = = zero pair = -2 -2 + (-3) = = -5
  6. 6. 2. Number Line 0 1 2 3 4 5 6 7 8-8 -7 -6 -5 -4 -3 -2 -1 - starts with the origin - 6 + 4 = -2 ADDITION OF INTEGERS
  7. 7. 2. Number Line 0 1 2 3 4 5 6 7 8-8 -7 -6 -5 -4 -3 -2 -1 Example: move 5 units to the left and 6 units to the right - starts with the origin - 5 + 6 = 1 ADDITION OF INTEGERS
  8. 8. 3. Rule: SAME SIGN, add and keep DIFFERENT SIGN, subtract. KEEP the sign of bigger number And it will be EXACT. ADDITION OF INTEGERS (absolute value) - 6 + 4 = 3 + 4 = (like sign) (unlike sign) vv 7 2- 6 + (-4) = -3 + (-4) = 7 2 - vv (common sign)
  9. 9. ADDITION OF INTEGERS 2. -7 + 10 = 1. 3 + (-5) = 2 3 4. 8 + (-4) + 3 = 3. -3 + (-2) = 5 11 - + (-4) = 7 - 5. 2 + (-5) + (-3) = 2 + (-8) = -6
  10. 10. Test Yourself. 2. -70 + 15 = 1. 3 + (-7) = 4. 4 + (-6) + 8 = 3. -14 + (-20) =- 5. 10 + (-1) + (-4) =
  11. 11. Answer Key 1. -4 2. -55 3. -34 4. 6 5. 5
