1. The problem is to multiply 2,821 by 3. 2. Write the multiplication: $$2821 \times 3$$ 3. Multiply each digit of 2821 by 3: - $1 \times 3 = 3$ - $2 \times 3 = 6$ - $8 \times 3 = 24$ (write 4, carry 2) - $2 \times 3 = 6$, plus the carry 2 equals 8 4. Combine the results to get the final product: $$8463$$ Therefore, $$2821 \times 3 = 8463$$.
