ALT A maths puzzle graphic titled “Broken magic square.” The instructions explain that the square is incorrect and that all rows, columns, and diagonals should add to the same total. The task asks which number is wrong and what it should be. In the centre is a 5×5 grid of numbers, arranged as follows: Top row: 180, 187, 164, 171, 173 Second row: 166, 168, 175, 182, 184 Third row: 177, 179, 168, 163, 170 Fourth row: 183, 165, 172, 174, 181 Bottom row: 169, 176, 178, 185, 167 To the right, text invites the viewer to create another “Broken magic square” to challenge a friend. At the bottom, a progress-style bar shows Calculator Crunch with labelled steps from Day 1 to Day 5, and the MEI logo appears in the bottom-right corner. The design includes soft green and blue geometric shapes in the background.
