### Unit Learning Outcomes

1

Understand algebraic expressions.

#### Assessment Criteria

• 1.1

Distinguish the different roles played by letters, knowing what letter symbols represent in equations, formulae and identities.

• 1.2

Manipulate algebraic expressions by taking out common factors and factorising quadratic expressions

This may include the difference of two squares, reciprocal functions and cancelling common factors in rational expressions.

• 1.3

Set up and solve simple equations by using inverse operations or by transforming both sides in the same way.

• 1.4

Solve linear equations.

This includes:

a. equations in one unknown, with integer or fractional coefficients, in which the unknown appears on either side or on both sides of the equation

b. equations that require prior simplification of brackets, including those that have negative signs occurring anywhere in the equation, and those with a negative solution
