Mnemonics are various techniques and methods for storing information based on the properties of the psyche and facilitating the strengthening of certain types of information in memory. Using these techniques, you can quickly and firmly memorize phone numbers, dates and numbers.
1. Alphanumeric code. The essence of this method is that each number is attributed a certain consonant letter. For example: 0 - H, 1 - P (times), 2 - D, 3 –T, 4 - H, 5 - P, 6 - W, 7 - C, 8 - B, 9 - M ("many", t.k. D is already taken). To remember a single digit, you need to take the letters corresponding to it and make a word. 29 - D + M = HOUSE. To remember a large number, you need to break it into such words and make up a phrase that you need to remember.
There are more complex variations of the alphanumeric code. For example, the code according to V. Kozarenko: 1 - GZ; 2 - DT; 3 - KH; 4 - HH; 5 - PB; 6 - HL; 7 - SZ; 8 - WF; 9 - RC; 0 - MN.
Alphanumeric code according to T. Buchan: 1 - TD; 2 - H; 3 - M; 4 - H; 5 - BP; 6 - SH; 7 - HA; 8 - WF; 9 - PSU; 0 - AP.
Of course, the alphanumeric code needs to be well learned and to know it as a multiplication table. In my opinion, the first method is the easiest in everyday use, because you don’t need to memorize the first letters of numbers, you just need to adapt quickly to find the right words for memorization and put them into phrases.
2. Shedd system. Each digit is assigned a word containing the number of letters equal to the digit. For example: how to (3) learn (7) the number (5) - 375. The number 0 can correspond to words of 10 letters or punctuation marks. 3750 - how to learn a number? (? = 0), or "how to learn a number effectively" (10 letters correspond to 0).
3. Assigning numbers to images. The two are like a swan, the eight is like an infinity sign. To remember the number 28, you can imagine a swan carving an infinity sign on the surface of the water. This method has a significant minus: when remembering the number 82, we can imagine the same image, and confuse the numbers in places.
4. Associations with numbers. We have 5 fingers on the hand, and 7 colors in the rainbow. A similar value can be assigned to all numbers. And it turns out: number 57 - a hand holding a rainbow.
5. Finding relationships with familiar dates and numbers. The number 3112 is easy to remember by relating it to the date of the last day of the year, 803 to international women's day, etc.
