That you can't continue to use a variable from an intermediate result that
has overflowed, since it's garbage. This means ordering your calculations
so the answers always fit within the variable's type. (As you later
explained, that doesn't preclude algorithms that take a new direction upon
realizing an upcoming overflow.)
