This exercise in BIDMAS/BODMAS allows learners to explore calculations using just four 4s. The tns file has calculator, notes and lists and spreadsheet pages to allow learners to create and check calculations with answers from 1 to 100. The challenge to achieve all of the target numbers leads students to investigate a wide range of operations.
