That is, we need to know what we're dealing with when working with these problems. We need to know B's age currently, but it gives us information about the future (A's age will be...). When we operate on the equations we are going to use, we need to make sure we know if we're talking about the future or present. It would be advantageous to try to stick to one time as much as we can. That is, it would be of great help to rewrite all terms in the present mindset or future mindset. In this problem we'll stick with the present method.\r<BR>\n" );
