Rules for Adding and Subtracting Integers

Mastering integer addition and subtraction hinges on understanding a few key rules. For addition, if the signs of the integers are the same (both positive or both negative), add their absolute values and retain the original sign. For example, 5 + 3 = 8 and -5 + (-3) = -8. If the signs differ, subtract the smaller absolute value from the larger and keep the sign of the integer with the larger absolute value. For instance, 7 + (-3) = 4 and -7 + 3 = -4.

Subtraction of integers is elegantly simplified by converting it to addition. Change the subtraction sign to addition and reverse the sign of the second integer. Then, apply the rules of integer addition as described above. So, 5 ⸺ 3 becomes 5 + (-3) = 2, and -5 ー 3 becomes -5 + (-3) = -8. Similarly, 5 ⸺ (-3) transforms into 5 + 3 = 8, and -5 ⸺ (-3) becomes -5 + 3 = -2.

Consistent application of these rules, coupled with ample practice using worksheets, solidifies understanding and builds proficiency in adding and subtracting integers. Remember, visualizing these operations using number lines or integer chips can greatly aid comprehension, particularly for those initially grappling with these concepts. The combination of understanding the rules and consistent practice leads to mastery.
