These cards contain some of the key terms and skills you will need to answer algebra questions. Copy down the ones you need or ask your teacher for a printout. What does term mean?What does simplify mean? A ‘small’ chunk of algebra, e.g. 7yCollect like terms or cancel What does solve mean?What is an equation? In the case of an equation, find the value (or values) of the unknown Two expressions with an = sign between them How do you solve equations?What does expression mean? By getting the unknown on its own on one side of the equation by using inverses or doing the same to both sides a ‘larger’ chunk of algebra with multiple terms joined by operations, e.g. 3p − 7y How do you simplify expressions? How do you substitute? By doing the sums that you can do i.e. collecting like terms Replace the letters in an expression or formula by numbers Algebra GFED Situation – Test yourself cards
