Every visible word and source relationship is available below. Read only the selected useful part; retain complete access. Paper, usual communication and adult-directed exact recording require no colour, vision, touch, printer or device. Ordinary models and held-source own aids are explicitly separate; keep keys and reserves unseen.

Every visible word in order:

1. A trade that keeps the amount: model

2. Read, draw, say, sign or direct. One useful part can be enough.

3. MODEL · 405 = 4 hundreds + 0 tens + 5 ones

4. 405 = 3 hundreds + 10 tens + 5 ones

5. 400 + 0 + 5 = 300 + 100 + 5

6. Trade one hundred for ten tens; keep the amount.

7. Zero means no tens in the standard form.

8. A nonstandard count can exceed 9 without changing value.

9. hundreds
