1. The problem is to calculate the product of 33 and 33. 2. We use the multiplication formula: $$a \times b$$ where $a=33$ and $b=33$. 3. Multiply the numbers directly: $$33 \times 33$$. 4. Calculate step-by-step: - Multiply 3 (units digit) by 33: $$3 \times 33 = 99$$. - Multiply 30 (tens digit) by 33: $$30 \times 33 = 990$$. 5. Add the partial products: $$990 + 99 = 1089$$. 6. Therefore, the final answer is $$33 \times 33 = 1089$$. This method breaks down multiplication into simpler parts and then sums them to get the final product.
