Evaluate Algebraic Expression Worksheets (1 variable)

There are four sets of evaluate algebraic expressions worksheets:

• Algebraic Expressions with 1 Variable (positive numbers)
  
• Algebraic Expressions with 1 Variable (integers)
  
• Algebraic Expressions with 2 Variables (positive numbers)
  
• Algebraic Expressions with 2 Variables (integers)
  

Examples, solutions, videos, and worksheets to help Grade 7 and Grade 8 students learn how to evaluate algebraic expressions with one variable (substitute positive numbers).

How to Evaluate Algebraic Expression (substitute positive numbers)?

There are two sets of Evaluating Algebraic Expression worksheets.

• Evaluate Algebraic Expression (add, subtract, multiply, divide).
• Evaluate Algebraic Expression (parenthesis, exponents).

These are the steps to evaluate algebraic expressions:

1. Substitute the variables with their provided values.
2. Use the order of operations (PEMDAS/BODMAS) to carry out operations in the correct sequence.

• Parentheses: Evaluate expressions within parentheses first.
• Exponents: Compute any exponents or powers.
• Multiplication and Division: Perform these operations from left to right.
• Addition and Subtraction: Perform these operations from left to right.

Example:
Evaluate the expression 3x 2 + 5 when x = 4.
Substitute x with 4: 3(4) 2 + 5
Compute the exponent first: 3(16) + 5
Perform multiplication and addition: 48 + 5 = 53

Remember to follow the order of operations and simplify each step along the way to evaluate the algebraic expressions accurately.
