ATCM 2008 ATCM 2008, the 13th Asian Technology Conference in Mathematics, will be held between 15 December and 19 December 2008 at Suan Sunandha Rajabhat University, Bangkok, Thailand. ATCM 2008 will continue addressing technology-based issues in all Mathematical Sciences. Thanks to advanced technological tools such as computer algebra systems ( CAS), interactive and dynamic geometry, and hand-held devices, the effectiveness of our teaching and learning, and the horizon of our research in mathematics and its applications continue to grow rapidly.

Histogram A histogram is a representation of a frequency distribution by means of rectangles whose widths represent class intervals and whose areas are proportional to the corresponding frequencies. We can built as simple histogram for groups of numbers according to how often they appear. Thus if we have the set {1,2,2,3,3,3,3,4,4,5,6}, we can graph them like this: This graph is pretty easy to make and gives us some useful data about the set.
