After being introduced to the rod numerals ...

The Chisanbop system. When a finger is touching the table, it contributes its corresponding number to a total. Chisanbop or chisenbop (from Korean chi (ji) finger + sanpŏp (sanbeop) calculation [1] 지산법/指算法), sometimes called Fingermath, [2] is a finger counting method used to perform basic mathematical operations.
The Chinese word for metre is 米 mǐ; this can take the Chinese standard SI prefixes (for "kilo-", "centi-", etc.). A kilometre, however, may also be called 公里 gōnglǐ, i.e. a metric lǐ. In the engineering field, traditional units are rounded up to metric units. For example, the Chinese word 絲 (T) or 丝 (S) sī is used to express 0.01 mm.

Moving the batch of rods representing 9 to the left one position (i.e., to the tens place) gives 9[] or 90. Shifting left again to the third position (to the hundreds place) gives 9[][] or 900. Each time one shifts a number one position to the left, it is multiplied by 10. Each time one shifts a number one position to the right, it is divided ...
The odd and even numbers alternate in the periphery of the Lo Shu pattern; the four even numbers are at the four corners, and the five odd numbers (which outnumber the even numbers by one) form a cross in the center of the square. The sums in each of the three rows, in each of the three columns, and in both diagonals, are all 15.
