%0 Journal Article %T Matrices and Division by Zero z/0 = 0 %A Tsutomu Matsuura %A Saburou Saitoh %J Advances in Linear Algebra & Matrix Theory %P 51-58 %@ 2165-3348 %D 2016 %I Scientific Research Publishing %R 10.4236/alamt.2016.62007 %X In this paper, a new viewpoint of the division by zero z/0 = 0 in matrices is introduced and the results will show that the division by zero is our elementary and fundamental mathematics. New and practical meanings for many mathematical and physical formulas for the denominator zero cases may be given. Furthermore, a new space idea for the point at infinity for the Eucleadian plane is also introduced. %K Division by Zero %K z/0 = 0 %K Field %K Y-Field %K Point at Infinity %K Infinity %K Matrix %K Cramer¡¯s Law %K Area %K Volume %K Parallel Lines %K Degeneracy of Figures %K Hooke¡¯s Law %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=67301
