Abstract
Many mathematical problems have been solved in more than one way that all of which are reasonably lead to the same answer but the solutions have completely different views. In this paper a method is presented for calculating the square of two-digit numbers and theirs process are interesting. Although the method proposed by the Author is more complicated than the usual natural one, but this research is very nice to foster a love of mathematics for elementary and middle school students for forming an interesting pattern and a triangle-shaped flat wake.
