Rules of addition and subtraction of integers

The rules of addition and subtraction of integers are fundamental concepts in mathematics that every student should understand. When adding integers with the same sign, simply add their absolute values and retain the sign. For example, -3 + (-2) = -5. When adding integers with different signs, subtract the smaller absolute value from the larger one and use the sign of the larger integer. For example, -6 + 3 = -3. When subtracting integers, we add the opposite of the second integer to the first integer. For example, 5 - (-7) = 5 + 7 = 12. It's important to know and apply these rules to avoid making errors and to understand more advanced concepts in algebra and calculus.
