| Question | Answer |
|---|---|
| What are good grades plus good grades? | MORE good grades (MORE means to add) |
| What are bad grades plus bad grades? | MORE bad grades (MORE means to add) |
| What do you do if you have good grades and bad grades? | SUBTRACT and good or bad depends on what has the most |
| What are 8 good grades plus 4 more good grades? | 12 good grades |
| What are 5 bad grades plus 6 bad grades? | 11 bad grades |
| What if you have 3 good grades and 7 bad grades? | You subtract, so you have 7 - 3 = 4 bad grades (bad because you had more bad grades) |
| What if you have 8 good grades and 2 bad grades? | You subtract, so you have 8-2 = 6 good grades (good because you had more good grades) |
| Apply the same concepts with negative and positive integers. | Positives are like Good grades and Negative are like Bad grades |
| 12 + 9 = (Think 12 good plus 9 good . What is good stuff plus good stuff?) | 21 (good plus good is MORE good, so you added 12 and 9 and it stayed positive since it was good.) |
| -12 - 20 = (Think 12 bad plus 20 bad. What is bad stuff plus bad stuff?) | -32 (bad plus bad is MORE bad, so you added the 12 and 20 and it stayed negative since it was bad.) |
| 15 - 18 = (Think 15 good and 18 bad. What do you do when you combine good and bad stuff?) | -3 (subtract 15 and 18 and keep the sign of negative because you had MORE bad stuff than good stuff) |
| -8 + 20 = (Think 8 bad and 20 good. what do you do when you combine good and bad stuff? | 12 ( subtract 8 and 20 and keep the sign of positive because you had MORE good stuff than bad stuff) |
| One last time. good plus good = | MORE GOOD |
| bad plus bad = | MORE BAD |
| good plus bad or bad plus good | Subtract and Keep the sign of whatever you had the most |
| 3 + 8 = | 11 |
| -6+9 = | 3 |
| -4 - 11 | -15 |
