Replacing each variable with a number in an expression and simplifying the result?
Substituting a numerical value for each variable in an expression and then simplifying the resulting expression is known as evaluating the expression. This process involves following the order of operations, which includes performing operations inside parentheses first, then exponents, multiplication and division from left to right, and finally addition and subtraction from left to right. By replacing variables with specific numbers, we can determine the exact value of the expression based on those inputs.
