The main content of Plimpton 322 is a table of numbers, with four columns and fifteen rows, in Babylonian sexagesimal notation. The fourth column is just a row number, in order from 1 to 15. The second and third columns are completely visible in the surviving tablet. However, the edge of the first column has been broken off, and there are two consistent extrapolations for what the missing digits could be; these interpretations differ only in whether or not each number starts with an additional digit equal to 1. With the differing extrapolations shown in parentheses, these numbers are:
| (1:)59:00:15 | 1:59 | 2:49 | 1 |
| (1:)56:56:58:14:50:06:15 | 56:07 | 1:20:25 | 2 |
| (1:)55:07:41:15:33:45 | 1:16:41 | 1:50:49 | 3 |
| (1:)53:10:29:32:52:16 | 3:31:49 | 5:09:01 | 4 |
| (1:)48:54:01:40 | 1:05 | 1:37 | 5 |
| (1:)47:06:41:40 | 5:19 | 8:01 | 6 |
| (1:)43:11:56:28:26:40 | 38:11 | 59:01 | 7 |
| (1:)41:33:45:14:03:45 | 13:19 | 20:49 | 8 |
| (1:)38:33:36:36 | 8:01 | 12:49 | 9 |
| (1:)35:10:02:28:27:24:26 | 1:22:41 | 2:16:01 | 10 |
| (1:)33:45 | 45 | 1:15 | 11 |
| (1:)29:21:54:02:15 | 27:59 | 48:49 | 12 |
| (1:)27:00:03:45 | 2:41 | 4:49 | 13 |
| (1:)25:48:51:35:06:40 | 29:31 | 53:49 | 14 |
| (1:)23:13:46:40 | 56 | 1:46 | 15 |
It is possible that additional columns were present in the broken-off part of the tablet to the left of these columns. Conversion of these numbers from sexagesimal to decimal raises additional ambiguities, as the Babylonian sexagesimal notation did not specify the power of the initial digit of each number.

Famous quotes containing the word content:
“For the first time I’m content to see
What poor mortar and bricks
I have to build with, knowing that I can
Never in seventy years be more a man
Than now a sack of meal upon two sticks.”
—Philip Larkin (1922–1986)
“First it must be known that only a spoken word or a conventional sign is an equivocal or univocal term; therefore a mental content or concept is, strictly speaking, neither equivocal nor univocal.”
—William of Occam (c. 1285–1349)
“Thoughts tending to content flatter themselves
That they are not the first of fortune’s slaves,
Nor shall not be the last, like silly beggars
Who, sitting in the stocks, refuge their shame
That many have and others must sit there,
And in this thought they find a kind of ease.”
—William Shakespeare (1564–1616)
