This Evaluate Expressions with Exponents Game is a great way to put your skills to the test in a fun environment. By practicing, you’ll start to work out the answers efficiently.
Evaluate Expressions with Exponents Game
This game is a step up in difficulty from the evaluate expression game which do not have exponents.
To evaluate expressions with exponents, first substitute the variable’s value into the expression, using parentheses to maintain proper order, especially for negative numbers. Then, use the order of operations (PEMDAS/BODMAS) to simplify the expression. Scroll down the page for a more detailed explanation.
This game generates a random expression that has exponents and two variables and challenges you to substitute values for the variables and calculate the correct answer. If you give a wrong answer, the game will provide the correct answer.

How to Evaluate Expressions with Exponents
To evaluate expressions with exponents, first substitute the variable’s value into the expression, using parentheses to maintain proper order, especially for negative numbers. Then, use the order of operations (PEMDAS/BODMAS) to simplify the expression: Parentheses, Exponents, Multiplication and Division (from left to right), and finally Addition and Subtraction (from left to right).
Evaluate Expressions with Exponents
- Substitute the given value for the variable into the expression. Be sure to place the value in parentheses to properly handle negative signs when they are raised to a power.
Example: If x = -5, and the expression is x², substitute as (-5)² not -5². - Evaluate the exponent. The exponent indicates repeated multiplication of the base number.
Example: In 2x² (where x = -4), evaluate (-4)² first: -4 × -4 = 16. The expression becomes 2(16). - Perform multiplication and division, working from left to right.
Example: 2(16) becomes 32. - Perform addition and subtraction, working from left to right.
Example: If you had 3x² - 3x - 5 for x = -4, after evaluating the exponent, it would be 3(16) - 3(-4) - 5.
Next, do the multiplication: 48 - 3(-4) - 5.
Then, the other multiplication: 48 - (-12) - 5.
Then perform the subtraction and addition from left to right: 48 + 12 - 5 = 60 - 5 = 55.
The video gives a clear, step-by-step approach to evaluate algebraic expressions with exponents using substitution.
