Binary numbers are the numbers 0 and 1 arranged in an arbitrary sequence. Memorizing binary numbers is a challenge for everyone, even people who have already gained a certain amount of skill in this area. Although you might at first think it is impossible, this task is theoretically no different from memorizing numbers.

Before we move on, we must do a little preparation so the binary numbers can be assigned to a variety of interesting pictures with relatively little effort. Few people would want to memorize such numbers using the master system (that is, with sea for 0 and tea for 1) in an alternating sequence. Therefore, it is important to find a system with which you can turn as many numbers as possible into a single image.

Today, binary numbers are most often associated with computer function rather than with their mathematical usage. In that usage, they are another way of writing the potentials of the number 2. Here you will find all the three-digit binary numbers for the corresponding Arabic numerals from 0 to 7.

0—0 0 0          2—0 1 0    4—1 0          0 6—1 1 0
1—0 0 1          3—0 1 1     5—1 0 1          7—1 1 1

Th e three-digit binary numbers can, of course, be easily converted into Arabic numerals and memorized (A Detailed Post On How To Use Your Imagination To Improve Your Memory ), but seven different pictures offer too little variety for remembering thousands of numbers in the correct sequence. It is also very tedious to learn to read seven to eight-digit binary numbers as Arabic numerals; in other words, you would automatically know that 01001011 corresponds to 75 and could turn the Arabic back to binary just as quickly.

I prefer the middle ground, breaking up a six-digit binary number into two three-digit numbers. I read the binary sequence 100110 as 100 and 110, then turn these two numbers into Arabic numerals (in this example, 4 and 6, making the number 46), which I remember using the master system. You can see what I meant about this being a challenge.

Impressive results have been achieved in this discipline in the World Memory Championships. The world record, set in 2007, was 4,140 numbers after only half an hour of memorization time.

Exercise To Practice Memorizing Binary Numbers

Change the following forty binary numbers into seven two-digit numbers using the method I described, and write the Arabic numerals on the lines provided. Take your time. One small piece of advice, draw vertical lines between each three-digit group to ease the conversion. Then try to memorize the numbers with the help of pictures. Once again, a suggested story is provided at the end.

0 0 1 0 0 0 1 0 1 0 1 0 0 1 1 0 0 1 1 1 1 1 0 1 1 0 1 0 1 1 0 1 1 1 0 1 1 1 0 1 1 1

Now cover the original row of numbers and write down as many as you can. No peeking!

Exercise 2

If you want to do more, recode the suggested solution into Arabic numerals and write them as binary numbers as a repetition exercise.

Suggested Solution

A tooth balances on a line and then jumps onto a mat. A piece of coal, however, mischievously covers it with lime juice and stuffs all the mail in his cheek!
