Strategy guide
- 1.Count the closed circles in each digit: 1 has 0, 9 has 1, so 4 has 1 circle;
- 2.Ignore mathematical operations and focus on the visual properties of the numbers;
- 3.Look at how each digit is written - closed loops determine the answer.
Common mistakes
- 1.Thinking it's a simple arithmetic sequence like 1+8=9, then 9+8=17;
- 2.Looking for a pattern in the numbers themselves rather than their visual presentation;
- 3.Counting the number of circles in the digits incorrectly or missing the pattern.
