Solving problems is what eight-year-old Terysa loves to do. So, when both she and her sister Kelia both have big math competitions coming up, can Terysa find a solution that will help them both? Luckily, no problem is too big for Terysa. So, with a little help from Kelia, she comes up with a plan to write an app to submit her math homework. Who knew that the computer could do math? Together, Kelia and Terysa learn how to code in Python to create a multiplication machine that prints out times tables! But can the times-table machine also help Kelia with her big quiz bowl competition? Will their team be fast enough to win the top prize? And what will Terysa's teacher, Mrs. Boxie, think of the problem-solving machine that Terysa has built?
