The person and the work
Biography
Sun Tzu the Mathematician was author of a Chinese mathematical manual associated with China. The Sunzi Suanjing includes arithmetic algorithms, measurement problems, and the remainder problem later called the Chinese remainder theorem.
The famous remainder puzzle reconstructs a number from its remainders under several divisors. Together, these contributions connect arithmetic, algebra and functions, and number sense to the working problems, tools, and questions of the period.

Core mathematical work
The Sunzi Suanjing includes arithmetic algorithms, measurement problems, and the remainder problem later called the Chinese remainder theorem.
Method, teaching, or application
The famous remainder puzzle reconstructs a number from its remainders under several divisors.
Why this matters
The larger lesson
Sun Tzu the Mathematician shows that mathematics grows through proof, calculation, observation, design, teaching, or careful records. The lasting lesson is that arithmetic, algebra and functions, and number sense can turn a difficult question into a method another person can inspect and reuse.

Key idea
An algorithm is a dependable sequence
Sun Tzu the Mathematician’s work illustrates how a clear sequence of operations turns a difficult task into repeatable calculation.
Following multiplication before addition gives 14 × 7 + 8 = 106.
Try it yourself
Follow the operation order
Calculate 14 × 7 + 8.
- Multiply first.
- Add the remaining value.
- Check by estimating the size of the result.
Show the answer
14 × 7 = 98, and 98 + 8 = 106.
Math at work
Merchants and business owners use the same habits
Merchants and business owners use arithmetic to plan, compare, test, or communicate decisions. Sun Tzu the Mathematician’s work provides a historical example of that connection.
