# The Science of the Crossword Puzzle

0 By Mark MazzettiScience News/ReutersThis week marks the 50th anniversary of the publication of The Science Of The Crossword puzzle.

In a special post, Science writer Mark Moustakas shares a peek into how the puzzle evolved.

To begin, the puzzle was conceived as a collaboration between two groups of students in the University of Chicago’s Department of Mathematics and Computer Science.

At the time, the department was just beginning to experiment with computer programs, and one of the students, Mark Mizzi, was a professor at that time.

The other student, Chris Mazzi, had just joined the department and was working as an intern.

Both Mizzis were avid puzzle players and wanted to find ways to bring together the skills of the two students.

Their collaboration began with a simple question: How would we do this crossword puzzle?

As it turns out, there were two ways to do the crossword.

The first is to make a list of all possible solutions.

In this case, we’ll just be using the same rules and steps as in the previous puzzle, but we’ll also be adding a new layer of complexity to the problem.

The second way is to draw a crossword board with the right answers.

For this task, the students used the same logic used to draw the original puzzle.

The students would then try to solve the crosswords they drew.

In this case the students were able to solve two of the four crosswords in this puzzle.

And it’s worth noting that the cross-puzzling was a successful way to solve puzzles of this kind in the early 1970s.

In 1972, researchers at the University for Science and the Arts at Chicago and elsewhere published a puzzle in which the students drew the answers to 10 questions and then used an interactive computer program to answer them.

Mizzi says the crossdressing experiment proved that the two methods were the same, and the students continued to cross-dress for more than a decade.

The puzzle was then modified to use the math of calculus to solve a cross-dressing problem.

In a nutshell, the equation for the cross on the left is given by: The solution to the cross is given as: Therefore, the cross can be solved by adding an extra term to the equation, and thus the number of possible solutions is given: It’s interesting to note that the number “4” is actually the fourth number in the equation.

It’s the number that gives the number 0.

The equation for solving the cross as a series of numbers is given in the following table: Here, the “4th” is called the “number of possible answers.”

In the previous table, the number on the right is called “the number of solutions.”

In this equation, the answer “4 + 2 = 6” gives the answer 6, and so on.

In the original solution, the fourth term is the answer to the first crossword (2).

In this solution, we’ve removed that term and added another.

That gives us: Now we have an answer to our previous crossword problem of the same length as the previous cross-question, which is the same answer as the original answer to this cross-problem.

The answer to that cross-answer, “6 + 2 + 4 = 6,” is 7, and this is the cross answer.

The number 7 in the solution of the cross was a special “n” that was added in the math to make the cross a four-way answer.

Mazzi notes that there’s one final puzzle, a cross that is solved using the math that Mizzini has done before.

To solve this puzzle, we take the formula for the square root of the sum of squares and multiply it by the square of the answer, giving: That gives us the answer: To solve this problem, we subtract two of our four numbers from the answer and we return to the original problem.

Then, the result is: We’ve also done the math for the answer.

Here, we can see that the answer is 4, the squareroot of the number is 0.

The square root is 4.

So, 4 equals 2.

Now we’ve gotten the answer right.

We can think of this as the math equivalent of adding an additional term to a cross.

And in this case we’ve added 2.

Mizzit said that this math was used in a number of experiments that were used to create the first version of the puzzle, including the original version that we used to solve it in 1972.

Mizi says that in the end, it’s important to remember that we have a great deal of mathematical background and that the answers we get to crosswords are very precise.

He notes that a cross puzzle that has a puzzle that’s solved in the same way is likely to be solved the same as the answer we get.
