set operations in $[officename]Math sets of numbers included in set operator not included in set operator owns command includes set operator empty set intersection of sets union of sets difference set operator quotient set cardinal numbers subset set operators superset set operators not subset set operators not superset set operators natural numbers whole numbers real numbers complex numbers; set rational numbers Set Operations Assign different set operators to the characters in your $[officename] Math formula. The individual operators are shown in the lower section of the Elements window. Call the context menu in the Commands window to see an identical list of the individual functions. Any operators not found in the Elements window have to be entered directly in the Commands window. You can also directly insert other parts of the formula even if symbols already exist for them.

After clicking the Set Operations icon in the Elements window additional icons will be shown in the lower part of this window. Simply click a symbol to incorporate the operator in the formula being edited in the Commands window. The set operations in detail: Icon is included in Use the icon to insert the is included in set operator with two placeholders. You can also enter <?> in <?> directly into the Commands window. Icon is not included in Use this icon to insert the is not included in set operator with two placeholders. You can also enter <?> notin <?> in the Commands window. Icon includes Use this icon to insert the set operator includes with two placeholders. You can also enter <?> owns <?> or <?> ni <?> directly in the Commands window. Icon empty set Use this icon to insert an empty set. Enter emptyset in the Commands window, in order to insert an empty set into your document. Icon Intersection Use this icon to insert two placeholders with the set operator intersection of sets . The same happens if you enter <?> intersection <?> Commands window. Icon Union Use this icon to insert the union set operator with two placeholders. You can also enter <?> union <?> directly in the Commands window. Icon Difference Use this icon to insert the difference set operator. You can also enter <?> setminus <?> or <?> bslash <?> in the Commands window. Icon Quotient set Use this icon to insert a slash for creating a quotient set with two placeholders. Enter <?>slash<?> in the Commands window, to achieve the same result. Icon aleph Use this icon to insert a cardinal number. You can achieve the same result by entering aleph in the Commands window. Icon Subset Use this icon to insert the is a subset of set operator. You can also enter <?>subset<?> directly in the Commands window. Icon Subset or equal to Use this icon to insert the is a subset or equal to set operator with two placeholders. You can also enter <?>subseteq<?> in the Commands window. Icon Superset Use this icon to insert the set operator is a superset of and two placeholders. You can also enter <?>supset<?> in the Commands window. Icon Superset or equal to Use this icon to insert the set operator is a super set or equal to with two placeholders. Alternatively, you can enter <?>supseteq<?> in the Commands window. Icon not subset Use this icon to insert the not subset set operator with two placeholders. Instead of this, you can also enter <?>nsubset<?>. Icon not subset or equal to Use this icon to insert the not subset or equal set operator with two placeholders. You can also enter <?>nsubseteq<?> in the Commands window. Icon not superset Use this icon to insert the not superset set operator with two placeholders. You can also enter <?>nsupset<?> in the Commands window. Icon not superset or equal to Use this icon to insert the not superset or equal set operator with two placeholders. Instead of this you can type <?>nsupseteq<?> in the Commands window. Icon Set of natural numbers Use this icon to insert a character for the set of natural numbers. Instead of this, you can enter setn in the Commands window. Icon Set of whole numbers Use this icon to insert a character for the set of whole numbers. You can also do this by entering setz in the Commands window. Icon Set of rational numbers Use this icon to insert a character for the set of rational numbers. You can also do this by directly entering setq in the Commands window. Icon Set of real numbers Use this icon to insert a character for the set of real numbers. Instead of this, you can enter setr in the Commands window. Icon Set of complex numbers Use this icon to insert a character for the set of complex numbers. You can also enter setc in the Commands window. Be sure to leave spaces (gaps) between values and commands when entering them manually in the Commands window. This ensures that the correct structure is achieved.
