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.

ALT A maths puzzle graphic titled “Only eights.” At the top, eight small boxes each display the number 8. The instructions ask: “Using only 8 eights and the calculation keys, how close can you get to 1,000? Can you make 1,000 exactly?” Two challenges are listed: Use only the plus, minus, multiply, and divide keys (shown as symbols +, −, ×, ÷). Extend the challenge by including square roots, powers (exponents), decimals, brackets, and factorials (with symbols such as √, x², parentheses, and ! shown alongside). A note at the bottom explains factorials, with the example: 4! = 4 × 3 × 2 × 1 = 24. Along the bottom, a progress bar shows Calculator Crunch with Day 1 to Day 5, highlighting Day 2, and the MEI logo appears in the bottom-right corner. The design includes soft green and blue geometric shapes in the background.
