Tiny BASIC is a dialect of the BASIC programming language that can fit into as little as 2 or 3 KB of memory. This small size made it invaluable in the early days of microcomputers in the mid-1970s, when typical memory size was only 4 to 8 KB. To meet these strict size limits, math was purely integer based and it lacked arrays. Read more on Wikipedia...
