The partial products are: 42 * 28 = (40 + 2)*(20 + 8) = 40*20 + 40*8 + 2*20 + 2*8 = 800 + 320 + 40 + 16
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.
