wrote the number one with one flat horizontal line 一. They found it hard to simplify this pictograph, so never changed its shape. It is pronounced ICHI either in compound words or by itself. It can also be pronounced HITOTSU (with a kana, since the kanji 一 only provides the HITO sound) either in compound words or by itself.
The number two followed the same pattern and was written 二. It is pronounced NI, either in compound words or by itself. It can also be pronounced FUTATSU (again with a kana, since the kanji 二 only provides the FUTA sound) in compound words or by itself.
The number three was done the same, and was written 三. It is pronounced SAN either in compound words or by itself. 三 can also be pronounced MITSU (with a kana) in compound words or by itself.
The number five started out the same, with five flat horizontal lines
The number four was pictured as four fingers balled into a fist
The number ten was pictured as the ten fingers of two crossed hands
The Chinese connected three tens
The Chinese tripled power 力力力 then multiplied by ten 十 to form the new composite kanji 協, many-strengths-together, meaning to unite, to join together in cooperation. 協 is not used as a word by itself. Used with other kanji in compound words it is pronounced KYŌ. The compound word 協力 KYŌRYOKU, unite-strength, means cooperation.
For number nine, the Chinese started with the number ten 十 and dropped one off
To symbolize the act of splitting or dividing, the Chinese drew a straight vertical line ┃, then divided it in two ||. It was stylized as
The Chinese drew a pictograph of the element for eight 八 and the element for two 二 escaping through the top to symbolize eight minus two, the number six. They wrote the final form of the kanji 六, meaning six. Used as word by itself it is pronounced ROKU or MUTSU. In compound words 六 is pronounced ROKU.

To form the kanji for a sword the Chinese drew a sword as
When 刀 is used as an element in a new kanji and appears in the left-hand or right-hand portion of the new kanji’s square, it is often abbreviated to 刂. When it appears at the top or the bottom of the new kanji’s square it remains 刀, although its proportions may change to fit the square. A 小刀, SHŌTŌ, is a short sword and a 大刀, DAITŌ, is a long sword.
The Chinese started with the sword 刀 then, onto the blade, added a mark ヽ to emphasize the meaning blade. They wrote the new kanji in final form like this 刃, meaning blade. Used as a word by itself it is pronounced HA. Used in compound words 刃 is pronounced JIN.
When 刀 sword is added as an element to the element for eight 八 (used in its meaning of divide) it forms the new kanji 分 meaning cut and divide. This kanji, 分, has many other meanings, but all subsume the idea of cut and divide. Used by itself, 分 is pronounced WAKARU (intransitive) or WAKERU (transitive). In compound words it is pronounced BUN, FUN or BU. The common word in Japanese for understand is 分 WAKARU (to cut and divide knowledge into bite-size bits so it can be absorbed).
Many Japanese words, particularly those in common language as spoken for millennia, have many exceptions to the rules of definition and pronunciation. For example, 分, a very common character, in compounds means a piece or part or division, after something has been cut and divided. 一分 IPPUN (changed from ICHIFUN for euphony), means one minute, a division of an hour. The same kanji written in the same way 一分 also has the specialized meaning of one-tenth, in which case it is pronounced ICHIBU. The compound word 十分, JIPPUN, ten-minutes, means ten minutes. The same two characters in the same order in another compound word 十分 are pronounced JUBUN, ten-parts-out-of-ten, which means enough, sufficient, adequate.
分子 BUNSHI, piece-child, means molecule. Pronounced exactly the same way, 分子 also means the numerator of a fraction. (The denominator of a fraction is 分母 BUNBO, mother-part.)
The Chinese took the Asian glyph for number seven
Then they added 七 seven to 刀 sword to get enough cutting power and made a new composite kanji 切, meaning cut. Used by itself it is pronounced KIRU. In combination with other kanji it is pronounced SETSU.
