The Cheprasov <ref>Cheprasov, Artem. ''On a New Method of Multiplication and Shortcuts''. Scotts Valley: Createspace, 2010'. Print.</ref> method of multiplication can be applied for any n digit number multiplied by any other n digit number and may involve negative steps even if two positive numbers are multiplied.
The basic algorithm, as best exemplified in a ''2'' • ''2'' multiplication problem, is as follows (where t represent a tens digit, u a units digit, and T the tens digit multiplied by its respective power):
: Step 1 = (t <sub>1</sub> - u <sub>1</sub>) • u <sub>2</sub>
