To learn a long number, combine two tools: the Major System to turn digits into pictures, and a journey to keep the pictures in order.
- Split the number into pairs (a final single digit uses a one-digit word).
- Turn each pair into its list word.
- Put one or two pictures at each spot on your route.
- To recall, walk the route and decode.
Worked example: Worked example
Learn 31415926 (the first eight digits of pi).
- Pairs: 31 · 41 · 59 · 26.
- Words: mat · rat · lip · notch.
- Route: front door (a mat), stairs (a rat), mirror (lips), sofa (a notch cut in it).
Answer: Four pictures on four spots.
Key idea
Pictures needed = digits ÷ 2, rounded up. Stops needed = pictures ÷ pictures per stop, rounded up.
Worked example: Counting stops
A 30-digit number with 2 pictures per stop. How many stops?
- 30 ÷ 2 = 15 pictures.
- 15 ÷ 2 = 7.5, round up.
Answer: 8 stops.
