This task involves creating questions from a given passage that involve some kind of complex reasoning (including numerical reasoning).
The generated questions must require looking at more than one part of the passage to answer. Try to use a variety of reasoning types in your questions (some of the sample reasoning types are illustrated in the 'positive examples' field) and also have a variety of answer types (spans, numbers, dates). A span is a continuous phrase taken directly from the passage or question. In such questions, the answer spans are recommended to be five words. Questions with answer type "number", are expected to start with "How many". For instance, "How long did an event last?" can be phrased as "How many years did an event last?". To increase diversity, try to create more questions for which the answer will be multiple spans. Please create questions that require AT LEAST 2 arithmetic operations as illustrated in the 'positive examples' field. You are encouraged to try DIFFERENT COMBINATIONS of operations and not just limit to the combinations shown in those examples. The more challenging questions you create, the better it is.

Passage: The San Antonio Spurs and the Lakers, developed what some would classify as a rivalry in the late 1990s and early 2000s. Since 1999, the teams have met in the NBA Playoffs five times, with the clubs combining to appear in seven consecutive NBA Finals (1999-2005). Additionally, the teams combined to win five NBA championships from 1999 to 2003. The Spurs won the NBA championship in 1999, 2003, 2005, 2007 and 2014 while the Lakers won the championship in 2000, 2001, 2002, 2009 and 2010. From 1999 to 2004 the clubs rivalry was often considered the premier rivalry in the NBA, and each time the clubs faced each other in the playoffs the winner advanced to the NBA Finals. In 2008 the teams met again in the Western Conference Finals where the Spurs were handily defeated only to beat LA when they met again in 2013 (though against a Lakers team without an injured Kobe Bryant).
How many combined championship wins did the Spurs and the Lakers have from the years 1999-2014?
