For the multiplication formula A*B, if A increases by 5 and B remains unchanged, the product of A and B increases by 60; if A remains unchanged and B increases by 6, then the product of A and B increases by 144. So, what is the original product?
乘法算式A*B，如果A增加5，B不变，则A与B的乘积增加60；如果A不变，B增加6，那么A与B的乘积增加144．那么，原来的乘积是多少？
