To the right, the "three-three" sequence|original: 條; tiáo results in eighteen; this number multiplied by itself|original: 自相乘; zì xiāng chéng yields three hundred twenty-four. Calculation: The "three-three" likely refers to a base of $3 \times 3 = 9$, which is then doubled to 18. Then $18^2 = 324$.
Divided among three people, one person receives one hundred and eight. Calculation: $324 \div 3 = 108$.

Two times two is|original: 如; rú four; The term "ru" (literally "as" or "like") is the standard term in ancient Chinese multiplication tables to indicate the result, functioning like an equals sign. this number multiplied by itself yields sixteen. Calculation: $2 \times 2 = 4$, then $4^2 = 16$.
Divided among two people, one person receives eight. Calculation: $16 \div 2 = 8$.

One times two is two; this number multiplied by itself yields four. Calculation: $1 \times 2 = 2$, then $2^2 = 4$.
One person receives four. Calculation: $4 \div 1 = 4$.

To the right, the "three-two" sequence results in six; this number multiplied by itself yields thirty-six. Calculation: The "three-two" refers to $3 \times 2 = 6$. Then $6^2 = 36$.
Divided among two people, one person receives eighteen. Calculation: $36 \div 2 = 18$.
