How to fill out evaluate numerical expressions

How to fill out evaluate numerical expressions:

1. Start by identifying the given expression. This can be in the form of a mathematical equation or word problem.
2. Break down the expression into its individual components. This may involve separating numbers, variables, and operators such as addition, subtraction, multiplication, and division.
3. Determine the order of operations to follow. The acronym PEMDAS is commonly used to remember the correct order: Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).
4. Evaluate any expressions within parentheses first. Simplify these expressions according to the order of operations.
5. Next, evaluate any exponents in the expression. If there are multiple exponents, calculate them one by one.
6. Proceed to solve any multiplication and division operations from left to right. If both operations are present, perform them in order from left to right as well.
7. Lastly, solve any addition and subtraction operations from left to right.
8. Double-check your work and simplify the expression if necessary.
9. Write the evaluated numerical expression as the final answer.
