Abstract
In this paper we will present a new construction of any real geometric (Clifford) algebra \({\mathbb {G}}^{(p,q)}\) with signature (p, q) where \(p+q=n\) by defining a product on the vector space \({\mathbb {R}}^{(2^n)}\) in a manner similar to Gauss’ ordered pair construction of the complex numbers (\({\mathbb {C}}\)) and Hamilton’s ordered quadruple construction of the quaternions (\({\mathbb {H}}\)). We will motivate the definition of a geometric product on \({\mathbb {G}}^{(p,q)}\) by generalizing the ordered tuple definition of multiplication on each of \({\mathbb {C}}\) and \({\mathbb {H}}\). Similar to the way in which Gauss obtains the basis \(\{1, i\}\) from the ordered pair definition of multiplication on \({\mathbb {C}}\), we will likewise derive a basis of monomials for \({\mathbb {G}}^{(p,q)}\) by multiplying those ordered \(2^n\) tuples that generate \({\mathbb {G}}^{(p,q)}\).
