Collecting Like Terms  This is where you would start. It is important to know which terms are 'like' and can be combined into one term.
Level 1  Simplify simple expressions by writing them in a more compact form
Level 2  Simplify some slightly more difficult expressions
Factorising  The next step is to understand how expressions can be simplified by factorising them.

"Don't know what key should be used for the multiplication sign with a German keyboard?"

Monday, December 21, 2015
"Hello Quasimodo4711 in Germany. None of the answers to this exercise require a multiplication sign. When two or more terms are multiplied together they can be shown without a sign. For example 6 times b is 6b and 5 times x times y times y is 5xy^{2}."
