Once you assemble the jigsaw puzzle, you'll need to decode Riley's message! But Zip's here to help! On the postcard in the box, Zip drops some useful tips to get you started. Here's the gist.
1. Note what you’re looking for Riley’s message will be a word or phrase. But it won’t be in plain sight! You’ll have to do something clever to get to it.
2. Note what’s going on Where Riley and Zip are and what they're doing hints at how you should decode. Riley and her freedom fighter pals are electrical engineers, so they aren’t going to send their message through interpretive dance.
3. Think of letters as numbers Riley’s a unique thinker—her brain often interchanges numbers with letters. So think of A as 1, B as 2, Z as 26, and vice versa. Which means you can also do math with letters! For example, A + D is E and 10 - 3 is G and Y + 2 wraps around to A, and so on.
4. Look for patterns Observe! Find examples in the assembled scene that demonstrate how things work, and use that knowledge to complete anything missing.
5. Get more help If you get stuck, don’t despair! Zip is available online 24/7 to provide detailed hints. You can also check if the answer you got is right, or read Riley's full explanation of the solution.

If you care enough to read the reviews on a puzzle book then this book is for you. Very eclectic collection of puzzles that will make you have to reach into every part of your mind to figure them all out.
This is the game for my family, my house, my life!
It’s a test of your brain to solve these puzzles. Glad to see there’s a second level book so I can continue along with more and increasing challenge.
I would definitely recommend this game to a teacher. [Proof! is] an awesome, fun game for students to engage in while learning math!

LOVE this game! [...] Fast moving and different. [...] A real thinking person's game. [...] Accessible for so many ages and abilities.
I, for one, am very pleased to see M again and have enjoyed reacquainting myself in this puzzle master's world.

My 7 year old, who loves math, was able to play the easy version while her 20 year old brother who majored in math played the hardest level and it was a fairly even competition.

Working the two Master Theorem books has been a joy - by far my favorite "puzzle books" of all time. Thank you (and the TMT team) for these incredible time-wasters!
