Callahan, Leroy G.; Charles, Desiree – Focus on Learning Problems in Mathematics, 1985
Previous studies indicate that many early elementary school children have the misconception that whole number subtraction is a commutative operation. The degree and character of this subtraction error was investigated in this longitudinal study. Results obtained from three groups of students with different number abilities provided further…

Perry, A. D.; Stacey, Kaye – Focus on Learning Problems in Mathematics, 1994
Attempted to establish the incidence of using taught algorithms versus invented methods of subtraction in (n=1,370) male secondary school students and to relate the use of invented methods to age, mathematical achievement, and lateral thinking ability. Use of invented algorithms increased with age. (23 references) (MKR)
