Grade 7 Math Worksheets

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).

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:

- Substitute the variables with their provided values.
- 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.
