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,
drop us a line
and we'll help you out. Be sure to tell us which challenge you're working on!
Show Hint
When you're trying to find a pair using only three cards, note that the result has to be either one of the cards already on the board or it has to be a square root of a number already on the board. Because if it wasn't already there, you'd need at least 4 cards to make it. So the only 13 possible results you could make are 49, 14, 2, 16, 33, 9, 36 1, and 23 as well as 7 (square root of 49), 4 (square root of 16), 3 (square root of 9), and 6 (square root of 36). See if you can make those 13 numbers using 3 cards each, and you'll solve this challenge!
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!
