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.

Show Hint
To find a particular pair, such as 50, a good trick is to try work backwards. Start with any number on the board, such as 100, and work backwards to figure out what you'd need to make 50. For example you could do 100 divided by 2. So now you just need to find a 2. Which you can make with 16 - 14. So there's your first 50. Now to make your second, pick another number, say 59, and work backwards from there to get to 50.
