An educational infographic titled 'The Sieve of Eratosthenes Explained', showing a step-by-step process to find all prime numbers up to 100 on a 10x10 grid. A column on the left details six labeled steps, including 'Circle 2, Cross Out Multiples' and 'Circle 3, Cross Out Multiples,' each with color-coded actions. On the 1-100 grid, numbers are circled in different colors or marked with colored 'X's according to these steps, effectively sifting out the composite numbers.At the bottom, a gold ribbon highlights the final set of prime numbers found: 2, 3, 5, 7, 11, and more, up to 97. The process is concluded when it is stated that 'Prime Numbers Remain up to $\sqrt{100}=10$'. To the right, a friendly cartoon illustration of Eratosthenes, wearing a toga, points to the grid and adds a final insight in a speech bubble: 'Only need to check up to the square root of the limit!'
