Make the Number: Math Workout

Place the correct signs between numbers to solve 3000+ tricky math puzzles.

Place arithmetic operation signs between numbers to solve 3000+ tricky math puzzles in 54 puzzle packs.

Did you know that you can make all numbers from 1 to 100 by placing +, −, ×, ÷ between the numbers 1, 2, 3, 4, 5, 6, and 7?

Make the Number: Math Workout features an original and interesting gameplay mechanic. You are given several numbers between which you should place addition, subtraction, multiplication, and division signs (+, −, ×, ÷) or question marks to make all possible numbers between 1 and 100.

If there is no sign between the numbers (a question mark means there is no sign), the numbers are merged together to form a number with more digits.

For example, 1 ? 2 × 3 - 4 equates to 12 × 3 - 4 = 32.

Thus, 1 and 2 are merged and form the number 12 together.

Our mathematical game is an easy way to practice addition, subtraction, multiplication, and division, as well as to memorize special numbers like powers of two, Fibonacci numbers, square numbers, and prime numbers.

If you like mathematics and puzzle games in which you need to try various options (Sokoban, Sudoku, Kakuro, Nonograms, number crosswords), you will love our game.

Math games related to placing arithmetic signs between numbers have been used in math education at least since the 19th century. Make the Number: Math Workout is similar to the educational arithmetic card game 24, which has been popular in US schools and Shanghai since the 1960s. But, our game mechanics are more challenging and allow the design of much trickier puzzles with more variations.

Besides, there is no time limit in our math puzzle because the puzzles are rather complex. So, take your time. The puzzles test your math logic and skill, not tapping buttons fast.

Our game contains the most comprehensive list of arithmetic puzzles. They will allow you to train your brain in solving math problems and boost your math superpowers.

Some of the puzzles in our game, for example, three or four number puzzles, are very easy and intended for kids. Five and six number puzzles provide a reasonable challenge. Other puzzles, composed of seven and eight numbers, are difficult even for adults. However, if you feel that ordinary puzzles are too easy for you, we dare to face the hardest nine and ten number puzzles.

Our game features a flexible system of hints. You can use two hints per puzzle. The first hint solves half of the signs. The second hint solves the puzzle completely. We recommend starting by solving the hardest puzzles after using a hint, because deducing eight or nine signs at once can be overwhelming.
