Problem 1 doesn't make sense ... 89^2 (ie 89 squared, or 89*89) = 7921, but your problem has 79@@, so I am not sure what's up with that.

]]>the symbol @ is a missing number and she has to replace it with a number to make the statement true.

1/ (@@)2 = 79@@

2/ (@@)3= 103 823

can anyone help a father in need plz.]]>
