Applications of integer operations

In this section, we will apply our knowledge of integer addition and subtraction to solve word problems. We perform integer operations in our daily lives, whether we are calculating how much money we spent at the store or figuring out how many minutes we have left before our bus arrives. Negative integers represent decreasing values or downward movements and positive integers represent increasing values or upward movements. We encounter negative and positive integers all around us. For example, we deal with these integers when talking about temperature, altitude, money and even hockey scores!
