Learn the method, follow the examples, then try the worksheet.
- 01
Combining like terms
Identify like terms and combine their coefficients while keeping unlike terms separate.
- 02
Substitution with signed/rational values
Evaluate expressions using signed and fractional values, with brackets to preserve negative inputs.
- 03
Multiplying/dividing algebraic terms
Multiply and divide simple algebraic terms by handling numerical and variable factors separately.
- 04
Expanding a single bracket
Expand a single bracket by multiplying every term, including signed terms, by the outside factor.
- 05
Factorising common factors
Reverse expansion by extracting the greatest common factor of every term.
- 06
Equivalent linear expressions
Compare linear expressions using valid algebraic transformations and distinguish equivalence from one matching value.
- 07
Rearranging simple formulas
Make a chosen variable the subject by undoing operations in reverse order on both sides.
