Strategy guide

1.Focus on making A equal 20 by dragging 13 from B to A, then tap A to answer;
2.Ignore the question text initially; concentrate on manipulating the numbers to reach 20 in A;
3.Remember the goal is to have A show 20, not to calculate an answer from the original values.

Common mistakes

1.Tapping on B instead of A after making 20, thinking the question refers to the original numbers;
2.Trying to solve mathematically without moving the numbers, overlooking the drag interaction;
3.Dragging the wrong number or to the wrong place, not realizing 13 from B to A creates 20.
