The correct product is 47 * 16 = 752.
You multiply 7 by 6 to get 42 (which you write as 2 in the bottom half and carry over the 4 to the top half), then multiply 7 by 1 to get 7, and add the carried over 4 to get 11 (which you write as 1 in the bottom half and carry over the 1 to the top half), then multiply 4 by 6 to get 24, and finally multiply 4 by 1 to get 4 and add the carried over 1 to get 5 (which you write in the top half).
Therefore, the product of 47 and 16 is 752.
