1. The problem is to multiply 99 by 25. 2. We can rewrite 99 as $100 - 1$ to make multiplication easier. 3. Using the distributive property: $$99 \times 25 = (100 - 1) \times 25 = 100 \times 25 - 1 \times 25$$ 4. Calculate each term: $$100 \times 25 = 2500$$ and $$1 \times 25 = 25$$ 5. Subtract the second term from the first: $$2500 - 25 = 2475$$ 6. Therefore, the product of 99 and 25 is $2475$.
