Matters needing attention

The cardinal number 13- 19 consists of single digits, with -teen added after the stem. Thirty, five and eight of them change irregularly.
Primitive words 20-90 are formed by adding -ty after a single digit. Among them, twenty, thirty, forty, five and eight change irregularly.
The radix 2 1-99 is composed of a ten-digit number followed by a single digit number and a hyphen "-"in the middle.
For example: 2 1 21,95 95.
For numbers with more than three digits, between 100 and 10 digits, the conjunction "and" is generally used, between 1 00000 and 1 100000 digits, and between100000 digits. For example: 132, one hungry, three hungry, two hungry, 1340, one hungry, forty hungry.
