  1. Integer Rules Tutorial AddSubtractMultiplyDivide Begin in “show mode”

  2. Integer Rules for Addition If two Integers have the same sign: Keep the sign and add the numbers! -3 + (-7) = -10 4 + 9 = 13 Exit PreviousNext

  3. Integer Rules for Addition If two Integers have different signs: Subtract the two numbers and keep the sign of the number with the highest absolute value! -3 + 7 = 4 15 + (-9) = 6 -7 + 2 = -5 Exit PreviousNext

  4. You try now! Will the answer be positive or negative? -7 + 10 PositiveNegative Exit Previous

  5. OOPS! 10 is greater than 7 and 10 is positive. So, the answer would be positive. Exit PreviousNext

  6. YES! You are RIGHT! The answer would be positive! Exit PreviousNext

  7. 14 + (-20) Which has the bigger absolute value? 1420 Exit

  8. No, 20 is bigger than 14. Exit Previous

  9. Yes! So, would the answer be positive or negative? 14 + (-20) PositiveNegative Exit

  10. No, the answer is negative because 20 is negative. Exit PreviousNext

  11. Yes!! You are correct! Exit PreviousNext

  12. -6 + 2 Which has the highest absolute value? 62 Exit

  13. No, 2 is not bigger than 6. Exit Previous

  14. Yes, 6 is bigger than 2! Would the answer be positive or negative? -6 + 2 PositiveNegative Exit

  15. No, 6 is bigger than 2 and the 6 is negative. PreviousNext Exit

  16. Yes! Great job! Exit Next

  17. If the two numbers have the same sign, add the numbers and keep the sign. If the two numbers have different signs, subtract. Then, take the sign of the number with the highest absolute value. Exit Next

  18. 67 + (-29) Would the answer be PositiveNegative Exit Previous

  19. No. 67 is bigger than 29 and it is positive. Exit PreviousNext

  20. Yes! You are doing a great job! Exit PreviousNext

  21. -3 + (-9) Would the answer be PositiveNegative Exit

  22. No. Both numbers are negative so the answer will remain negative. Exit PreviousNext

  23. Yes! Wow, you are getting this! Exit PreviousNext

  24. -82 + (-10) Would the answer be PositiveNegative Exit

  25. No. Both numbers are negative so the answer is negative. Exit PreviousNext

  26. YES!! The answer would be negative! Exit PreviousNext

  27. Now, decide if you should add or subtract. 14 + 21 AddSubtract Exit

  28. Yes! Both are positive so you would add! Wonderful job! Exit PreviousNext

  29. No. Both numbers are positive so you add. Previous Exit Review Rules

  30. If the numbers have the same sign, add. -3 + (-7) 4 + 2 If the numbers have different signs, subtract. 5 + (-7) -9 + 3 Exit Try Again

  31. -4 + (-8) Same sign? YesNo Exit

  32. Look again: -4 + (-8) Four is negative and eight is negative. They have the same sign. Next Exit

  33. They have the same sign, so you will AddSubtract Exit

  34. Yes! You would add and keep the sign! Next Exit

  35. No. Four and eight are both negative. They have the same sign so you add. Next Exit

  36. -17 + 12 Do you AddSubtract Exit

  37. Yes! GREAT job! PreviousNext Exit

  38. No. 17 is negative and 20 is positive. They have different signs so you subtract the numbers. Exit Next

  39. Subtracting Integers When subtracting Integers, look at each term and determine if it is positive or negative. Then, follow the Integer rules for addition! Exit PreviousNext

  40. -3 – 7 The first term is -3. The second term is -7. Remember: the subtraction sign is also a negative sign! Exit PreviousNext

  41. -3 – 7 Both terms are negative. Now, follow the Integer rules for addition! Same sign, so you… AddSubtract Exit

  42. You are absolutely RIGHT! Way to go! Next Exit

  43. No. You do not subtract because the two terms have the same sign. They are both negative, so you add the numbers and keep the sign. Exit PreviousNext

  44. 14 - 24 Do you AddSubtract Exit

  45. No. 14 is positive and 24 is negative. They have different signs, so you subtract. PreviousNext Exit

  46. Yes! You subtract since the two numbers have different signs! Exit PreviousNext

  47. When you are subtracting a negative number, you must distribute the negative sign FIRST! -3 – (-10) becomes -3 + 10 Next, follow the Integer rules for addition. Exit Next

  48. 7 – (-29) Becomes… 7 – 297 + 29 Exit Previous

  49. No. After distributing the negative sign, the problem becomes 7 + 29. Exit PreviousNext

  50. Yes! Great job! Exit Next
