The Proof! Math Puzzle Challenges play exactly like the
classic Proof! card game,
except here you're looking for a specific type of equation,
rather than just any equation at all.
First,
read the title
of the challenge to understand what you're looking for. You can click the
for a more detailed explanation.
Then, start solving it by
clicking a card, then a math symbol, and then another card
to combine those cards using that operation. Once you create
two or more cards with matching values
(called a pair, triplet, etc.)
that fit the bill for this challenge, you'll win!
Full instructions
for the classic game can be found here.
If you're stuck, first try clicking the
near the title of the challenge for a more detailed explanation
and an example of what you're looking for.
If you're still stuck, click "Show Hint" below to reveal the hint for this challenge.
If you're still having trouble after that,

To find a pair greater than 20, start by making any number greater than 20 (or choosing one already out there, such as 38). Then work backwards to create a pair for it. For example, let's say we want to create a pair of 38s. We've already got one out there, so we just need one more. There's a 10 out there too, which is somewhat close to 38, so we can make 38 if we can make a 28 that we can add to the 10. We can then make a 28 by doing 14 x √(64 - 60). Now keep at it, starting by randomly picking other numbers greater than 20 to be your target!
From the makers of Proof! comes the brand new math game, Adsumudi! Find the secret math path to Adsumudi's answer on each card by adding, subtracting, multiplying, and dividing the other numbers. Find it first and collect the card. Five cards wins!
