ADDING AND SUBTRACTING INTEGERS

In addition and subtraction of integers, we will learn how to add and subtract integers with the same sign and different signs. We can also make use of the number line to add and subtract signed integers. There are certain rules for integers that have to be followed to perform operations on them.
Adding two positive integers results in positive integers, whereas adding two negative integers will result in the sum with a negative sign. But, the addition of two different signed integers will result in subtraction only and the sign of the result will be the same as the larger number has. See a few examples below:
2+2 = 4
2 + (-2) = 0
-2 + (-2) = -4
-2 - (-2) = 0
Addition and subtraction
Addition and subtraction are two primary arithmetic operations in Maths. Besides these two operations, multiplication and division are also two primary operations that we learn in basic Maths.
The addition represents the values added to the existing value. For example, a basket has two balls, and if we add more than 2 balls to it, there will be four balls in total. Similarly, if there are four balls in a basket and if we take out two balls out of it, then the basket is left with only two balls, which shows subtraction.
Addition and subtraction are not only used for integers but also rational numbers and irrational numbers. Therefore, both the operations are applicable for all real numbers and complex numbers. Also, the addition and subtraction algebraic expressions are done based on the same rules while performing algebraic operations.
