  i knew urlLink google has some cool tricks in it but i totally missed the urlLink calculator and urlLink definitions . the calculator works just by typing an equation into the query field and searching on it. i'm not talking just addition, substraction, multiplication, or division here as well. it supports hexadecimal, octal, and binary math as well as a number of constants like urlLink Pi and urlLink c . a brief guide can be found urlLink here . make sure to check out the neat urlLink conversions you can do. the dictionary function works just by typing define:&lt;term> in the query field (like urlLink this ).
