– Explanation of addition in mathematics

The addition is a process of adding two or more items together. In math, addition is the method of calculating the total of two or more numbers to know the sum of the numbers.

Example of addition

An example of addition is: 5 + 11 + 3 = 19.

Example: If a = 7 and b = 8, find the value of a + b

To evaluate the expressiona + b, substitute the value of a as 7 and the value of b as 8 and add the numbers as shown below,

$a + b = 7 + 8 = 15$

Evaluate the expression x + 4 when x = 15

To evaluate the expression(x + 4), substitute the value of x as 15 and add the numbers as shown below,

When x = 15 and the expression x + 4

$\begin{array}{l} x + 4 \\ 15 + 4 \\ 19 \end{array}$

Thus, the value of the expression is 19.
