Great work! I'm delighted that you sent in
solutions to one of the "Calculator Equations" problems. All of those
problems have multiple solutions. And there are more for this one, as
Here's a challenge to readers: Traci's
second solution uses a zero (which is technically not allowed, since
no clue had a zero on it). Of course, most calculators will give the
right answer (one) whether you press the zero or not.
But then the decimal point is "cheap" in the
sense that you didn't use it to make a real decimal -- as she and her
group did in the first solution.
Can you find more solutions that use the
decimal point in order to make decimals?
