Peg the 10 (bowling ball) from the tree list to another peg such as your knee on the body list. For example, you could drop a bowling ball on your knee — ouch!

Peg the 1 (tree) from the tree list on your toe, then chain the 1 (tree) to a 0 (donut). For example, you kick the tree with your toe, breaking it, then the tree falls on top of a donut. That way, when you want to recall the number, look at your toe. You’ll see your toe kicking down the tree, and having it fall on the donut.

This technique works with a number of any length. Merely add numbers into your chain, or peg more numbers. (From now on, when referring to number memorization, the list that you use to CHANGE THE NUMBERS INTO PICTURES — such as the tree list — will be called the “Code List” and the list that you use to PEG THE ENCODED NUMBERS OR PICTURES ON will be called the “Number-Peg List.”) Of course, if your code list is only 20 items long, then you will only be able to peg two-digit numbers
with one picture if the number is below or equal to 20. (There’s no picture for 94, for example.) So, it’s not a bad idea to create a 100 item code list so that you can always memorize numbers two digits at a time. However, in the mean time, if the number is greater than 20, just peg them one digit per picture. (This is where chaining becomes very useful.)

Note: There is one particular specific that must be present in a list such as the tree list that is used as a code list. This is the number 0. There must be an item for 0, else there will be some numbers (such as 150) that could get tricky. Using 150 as an example, 15 on the tree list is a paycheck, however, there’s still a zero, so obviously, there must be an item for it. We use donut for the number 0 item on the tree list. (Think of a donut with the hole in the middle shaped like a zero.)
