Bronze Medal Winner in the Moonbeam Children's Book Awards and Story Monsters Approved. H.H. Tang is an Australian-born writer based in London. A former maths olympiad and career financial modeller, she was inspired to write a maths-based picture book when reading to her nieces and nephews. Passionate about maths as an important life skill, she wanted to write a book for young children in the early years of their education that involved numbers and was more challenging than simple counting.
