Hi. I keep forgetting how to achieve the desired result in Excel.

Say that I want a Cell (Let’s say, B1) to contain an initial value of 31, and as I add a number in A1, it decrements B1's value by 1, and the very minimum number is 1, so, if I put an outrageously large number (10,000), for instance, B1 still will have a value of 1.
