Lou Talman says:
>Here is one such problem, as given by Ma: "Mrs. Chen made
some tarts. She sold 3/5 of them in the morning and 1/4 of the remainder in the afternoon. If she sold 200 more tarts in the morning than in the afternoon, how many tarts did she make?"

LiPing Ma goes on to illustrate the "solution" as a working out of this "starting point" arithmetic expression: 200 % (3/5 - 1/4(1-3/5)).

What is the thought process that guides the formation of such an expression? Or, what is an English translation of that expression that relates naturally to the word problem as given? Is there any way to do so without mentioning the implicit "x"?

Cheers,
Joe N
