Magic Squares

What is a Magic Square?

A magic square is a square grid (normally 4×4) with numbers in each cell. The numbers in each row, column, and diagonal all add up to the same number. Normally in magic squares, the numbers in the cells are all different, and are the lowest numbers other than 0. Example: In a 4×4 grid, the numbers would be 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, and 16.

How to Construct a Magic Square

Ever tried—and failed—to understand binary?

Evan if you haven’t, here is the first Shufflenet Tutorial. The topic is: Binary.

What is binary?


Binary is a number system. The most common number system is base 10. It is the number system that humans use. We use it because we find it easy to use 10s. Just like it’s easy to memorize the 10 times table. Binary is a number system that instead of using 10 different numbers, it only uses 0 and 1. (Bi- means two, for the two different digits—0 and 1.)

Binary is what computers use. They find it easy because there are a very low amount—2—of different digits. Because there are only 2 different digits, this makes the binary number longer. Computer programmers currently  can only program computers that use binary. When you use the calculator app on your laptop, it converts the numbers to binary, solves the equation in binary, converts it back to base 10, and displays the answer for you to read.

How to do basic math in binary

Understanding binary is easy, but different from understanding base 10.
