SASMO questions are not standard school exam questions. They are "heuristic" problems. For example, a Grade 4 school exam might ask: "What is 15 + 8?" A SASMO question asks: "Using the digits 1, 2, 3, and 4 exactly once, what is the largest two-digit number you can make that is divisible by 7?" Practice papers familiarize the student with this "twist" in language and logic.
