Hi Michelle: First a few preliminaries based on the problem of displaying math via e-mail. 10^3 means 10 times 10 times 10 OR 10*10*10 OR 1000 3*4 means 3 times 4 OR 12 in the expression 3*10^1, the exponent part is done first OR 3*10 OR 30 10^0 by definition is equal to 1 10^(-3) is equal to .001 342.564 expressed as an expanded decimal would be: 3*100 + 4*10 + 2*1 + 5*.1 + 6*.01 + 4*.001 OR 3*10^2 + 4*10^1 + 2*10^0 + 5*10^(-1) + 6*10^(-2) + 4*10^(-3) 3.004 expressed as an expanded decimal would be: 3*1 + 0*.1 + 0*.01 + 4*.001 OR 3*10^0 + 0*10^(-1) + 0*10^(-2) + 4*10^(-3) I hope these examples will help your son understand expanded decimals. Cheers -Ron, for the T2T service
