New Interactive Problems in May 2024

It's that time of the month when I get to share an update on the list of topics that have had new interactive problems added in the previous month - in this case May. The update is split into changes published in our Australian textbooks and our US textbooks.

As always, if there's a chapter or topic that you think is in need of some new problems - because it's missing something, or just needs a greater range of questions - do let us know by sending a message to our support team via the chat icon in the Mathspace app.
