Subtraction of integer strategies: Students may already see that you can change a subtraction expression to addition by adding the opposite of the second number. Some may realize that when you are subtracting, you will get a positive answer if the number you start with is greater than the number you subtract. For example,  17   +   −   15   +   ,  17   +   −   1   −   , and  15   −   −   21   −   all give positive results. You will get a negative answer if the number you start with is less than the number you subtract. For example,  13   +   −   1   +   5   ,  1   −   −   1   +   5   , and  1   −   5   −   1   −   3   all give negative results. To find the value of the answer, you find the difference of the numbers. Some students will thin...
