The two partial products of 42 X 28 are 42 X 8 (336) and 42 X 2 (84). To get the actual answer, you shift the partial product (42 X 2) one decimal space to the left and add it to the other partial product, (42 X 8).
42 X 2 = 84. Now, shift 84 one decimal space to the left. This gives you 840.
42 X 8 = 336. Now add 336 to 840 to get the final result, 1176.

The partial products are: 42 * 28 = (40 + 2)*(20 + 8) = 40*20 + 40*8 + 2*20 + 2*8 = 800 + 320 + 40 + 16
34 x 28 = 34 x (20 + 8) First partial product is: (30 + 4) x 8 = 240 + 32 Second partial product is: (30 + 4) x 20 = 600 + 80 Sum of partial products = total product = 600 + 240 + 80 + 32 = 952
4 x 20 = 80 4 x 7 = 28 80 + 28 = 108 4 x 27 = 108
To find the partial products of 28 times 14, you would multiply each digit in the ones place of the second number (4) by each digit in the ones place of the first number (8), resulting in 32. Next, you would multiply each digit in the tens place of the second number (1) by each digit in the ones place of the first number (8), resulting in 8. Finally, you would add these two products together to get the final answer of 392.
