I want to second Ed's excellent message. Regardless of the 
repeatability of programs to execute correctly (is there a truly bug-
free program, conceptual and overlooked specifications included?) 
GIGO is a part of life. A computer program correctly produces the 
wrong answers if fed the wrong data. Mental arithmetic is highly 
useful. Who hasn't caught checkout operators and incorrect pricing in 
shops by doing a simple approximation in their heads?
