To calculate 42 x 92 using the lattice method, draw a grid with two rows (for the digits of 42: 4 and 2) and two columns (for the digits of 92: 9 and 2). Fill in each cell by multiplying the corresponding digits, placing the tens digit above the diagonal and the units digit below. Finally, sum the diagonals from right to left to get the final product, which is 3,864.
