## Historical Note

Started life as a women's interest magazine, but evolved into a magazine of riddles, puzzles and mathematical questions.

In its later years, many of the questions published therein were difficult, and attracted the attention of high-profile mathematicians of the time.

Many questions it published were ancient. For example:

- Question $42$ was a variant of Chiu Chang Suann Jing: Example 8.

- Question $51$ was taken from Diophantus of Alexandria:
*Arithmetica*Book $\text {V}$.

It was also frequently the case where the questions were taken directly from published sources, sometimes even mathematics textbooks.
