When Does a Subtraction Algorithm Involve Borrowing?

Peer reviewed

Kolb, John R. – Mathematics Teacher, 1982

Several subtraction algorithms are analyzed to see if they involve borrowing. The main focus is on an analysis of a procedure called the residue method. The operational arithmetic which underlies the symbolic manipulations is examined and conditions where the method does and does not use borrowing are highlighted. (MP)
