Mathematics: what was measured.
| Held-out problems | Right | Comparison |
|---|---|---|
| Addition | 200 of 200 | A version with no memory of the carry: 1 of 200 |
| Addition, subtraction and multiplication | 600 of 600 | |
| Division | 250 of 250 | |
| Fractions | 200 of 200 | |
| Rotations | 400 of 400 | |
| Linear equations | 200 of 200 | The same control: 0 of 200 |
| Quadratics | 200 of 200 | |
| Checking answers | 1,200 of 1,200 | 400 correct answers accepted, 800 wrong ones rejected |
Across about 3,600 held-out problems, the engine gave no wrong answer. In one set it could not compute 49 of 200 exactly, and said so instead of answering.
Size and recall
The four learned faculties (arithmetic, composition, algebra and quadratics) are stored together in 3,407 bytes. Learning them took 104 seconds on first start; after a restart they are available at once.
