Solution

Simplifying the expression using PEMDAS:
The order of operations is a rule that tells the correct sequence of steps for evaluating a math expression. We can remember the order using PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).
Use the rule of PEMDAS on the given expression to simplify it.
$\begin{array}{rcl} 24 \div 2 - 6 + 8 \div 2 & = & 12 - 6 + 4 \\ = & 6 + 4 \\ ∴ & = & 10 \end{array}$
Hence, the value of the given expression is $10 .$
