Bryant, Peter; Rendu, Alison; Christie, Clare
Journal of Experimental Child Psychology, v74 n3 p194-212 Nov 1999
Examined whether 5- and 6-year-olds understand that addition and subtraction cancel each other and whether this understanding is based on identity or quantity of addend and subtrahend. Found that children used inversion principle. Six- to eight-year-olds also used inversion and decomposition to solve a + b - (B+1) problems. Concluded that understanding may not be based on computational skills. (EV)
