Using Calculators to Discover Simple Theorems--An Example from Number Theory.

Padberg, Friedhelm F.

Arithmetic Teacher, v28 n8 p21-23 Apr 1981

Problems focusing on number theory that can make good use of the calculator in discovering and proving simple theorems are proposed. The focus is on the properties of subtracting the smaller of a three digit number and its mirror number from the larger in a process that leads to zero. (MP)
