Sets of Real Numbers
... Real Number- a number which can be written as a decimal. Rational Numbers- a number expressible in the form a/b or –a/b (fractions) including integers. Irrational Numbers- a number not expressible in the form a/b or –a/b and the decimal form is non repeating and non terminating. Integers- the number ...

... Difference between 'equation', 'formula', 'identity' and 'expression': an equation contains unknown quantities and can be solved for x e.g. 3x + 2 = 11; a formula links one unknown quantities to others e.g. A = 2r; an identity is true whatever the value of the unknown quantities e.g. 2(x + y) = 2x + ...
