Beaufort scale used in Taiwan and mainland China, which are often affected by typhoons. Internationally, WMO Manual on Marine Meteorological Services (2012 edition) defined the Beaufort Scale only up to force 12 and there was no recommendation on the use of the extended scale. Wind speed on the 1946 Beaufort scale is based on the empirical relationship: Where "v" is the equivalent wind speed at 10 metres above the sea surface and "B" is Beaufort scale number. For example, "B" = 9.5 is related to 24.5 m/s which is equal to the lower limit of "10 Beaufort". Using this formula the highest
Equate (game) ages 8 and up. The use of fractions stimulates the players interest towards fractions and motives them to want to learn more about fractions. In order to get higher scores, players are constantly taking advantage of premium board positions. Equate uses large numbers. Single digits placed adjacent to one another creates even larger numbers. Equate is also strategically challenging for advanced players who are already good at math. The game adapts to many different levels of play. Advanced Tile Sets take the game of Equate to a higher mathematical level. This particular sets includes 197 tiles with positive and negative
