What's the rule for adding and subtracting integers?

The rule of adding and subtracting integers (wholes numbers) is subtracting a negative number from another negative number equals a positive number while adding a positive and a positive is simple addition.

Now if you were to add a negative to a positive (-50 + 50), the sum would be 0 because you're basically taking away 50.

i dont know

step-by-step explanation:

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
