Find three different integers that have a sum of -12: -4 + -5 + -3 = -12. The integers are -4, -5, -3.

In football(yellow text question): Yes, they did earn enough yards to get a first down. If they have a chance to get 10 yards closer to their goal and Matt’s team gained 8, lost 4, and then gained 7. In total Matt’s team has gained 11 yards allowing them to advance. Since 8-4+7 is 11 (8-4 is 4. 4+7=11).

Find two different integers (purple text question): -70 + -2, together they have a sum of -72. The number sentence is -70 + -2 = -72.

Desert Question(teal text question): the difference between the two temperatures is 86. 136- -50 is 86. You subtract -50 from 136 because -50 is a negative.
