1. Multiply the 8 and 3 to get 24.Since 24 is greater than 9, you'll have to carry the 2.
2. Multiply the 5 and 3 to get 15.And, add the carried 2 to get 17.Since 17 is greater than 9, you'll have to carry the 1.
3. Multiply the 3 and 3 to get 9.
4. Multiply the 7 and 3 to get 21.21 is greater than 9, but there are no more digits to carry over, so just write the 2 down in front.
so the answer is 2,203,740
