y axis ___________________________________ The letters X, Y and Z often refer to unknown or "variable" quantities, and the purpose of solving the algebra problem is to determine the precise value of these variables.
Since "pre-" means before, then pre-algebra would be before algebra. Conversely, algebra would be after pre-algebra. Generally, the next class after a pre-algebra class would be Algebra I, followed by Algebra II.
Pre-algebra preps you for algebra.2nd answer:Pre-AP-algebra is the same as Algebra I. Both are way harder than pre- algebra.
Algebra may seem really stupid in school, but it does serve a purpose through life. For example if you had $x and you can get 40 litres of petrol, 1 litre costing $1.20? Here's how you do it using algebra. 1=$1.20 40=$1.20x40=$48 .'.x=$48 Hope this helps, but I suck at maths.
