Document Summary
Not so valid for matrice multiplicative properties t integers. T 1 2 but it does riot belong in 7l inverses integers do no t have. S is a an element set must be well defined no ambiguity a of s is denoted a c s d belongs to s sets. To describe list elements give a definingproperty words. Example s el 2,3 4 5 6 7 8 9. S t is a subset of 5 if each element of t belongs to s. 5h t elements that intersection the only set with no elements. Svt is the unio of s and t. Example si 41 ses te et alr is the. X f 1 1 c ir x ir y flx function is a relation. R between s and t is a subset of s xt. In a function each input corresponds to exactly one output the vertical line test.
