Fuzzy math is a catch phrase used often by politicians to describe numbers, particularly in regards to government spending, that they claim do not add up correctly. It is frequently used by politicians who are dismissing another politician's numbers as doubtful or otherwise inaccurate.[1]
The term "fuzzy math" was first heard during the debates prior to the 2000 US presidential election. It was used by future president George W. Bush, who dismissed the figures used by his opponent Al Gore. Others later turned the term against Bush himself.[1][2] The term has since been used by many other politicians in attacks against opponents or various beliefs, such as global warming.
