 Question: can you have a heart attack from laughing Context: These mnemonics may be misleading when written this way, especially if the user is not aware that multiplication and division are of equal precedence, as are addition and subtraction. Using any of the above rules in the order ``addition first, subtraction afterward'' would incorrectly evaluate the expression
 Question: is addition before subtraction in order of operations Context: There is some disagreement whether parallelograms, which have two pairs of parallel sides, should be regarded as trapezoids. Some define a trapezoid as a quadrilateral having only one pair of parallel sides (the exclusive definition), thereby excluding parallelograms. Others define a trapezoid as a quadrilateral with at least one pair of parallel sides (the inclusive definition), making the parallelogram a special type of trapezoid. The latter definition is consistent with its uses in higher mathematics such as calculus. The former definition would make such concepts as the trapezoidal approximation to a definite integral ill-defined. This article uses the inclusive definition and considers parallelograms as special cases of a trapezoid. This is also advocated in the taxonomy of quadrilaterals.
 Question: can a trapezoid have 2 sets of parallel lines Context: The film is based on Paul Brickhill's 1950 book of the same name, a non-fiction first-hand account of the mass escape from Stalag Luft III in Sagan (now Żagań, Poland), in the province of Lower Silesia, Nazi Germany. A heavily fictionalised version of the escape is depicted in the film. The film was based on the real events but with numerous compromises for its commercial appeal, such as including Americans among the escapees (none of whom were actually American). The characters are based on real men, and in some cases are composites of several men. However, many details of the actual escape attempt were changed for the film, and the role of American personnel in both the planning and the escape was largely fabricated. The Great Escape was made by The Mirisch Company, released by United Artists, and produced and directed by John Sturges.
 Question: was the great escape based on a real story Context: Sockeye salmon (Oncorhynchus nerka), also called red salmon, kokanee salmon, or blueback salmon, is an anadromous species of salmon found in the Northern Pacific Ocean and rivers discharging into it. This species is a Pacific salmon that is primarily red in hue during spawning. They can grow up to 84 cm (2 ft 9 in) in length and weigh 2.3 to 7 kg (5.1--15.4 lb). Juveniles remain in freshwater until they are ready to migrate to the ocean, over distances of up to 1,600 km (990 mi). Their diet consists primarily of zooplankton. Sockeye salmon are semelparous, dying after they spawn. Some populations, referred to as kokanee, do not migrate to the ocean and live their entire lives in freshwater.
