(4 × 2 = 8) Step 2: Multiply the tens digit 3 of the multiplicand by the ones digit 2. You now have 68 as the first partial product. Write zero under the first partial product’s ones digit. (3 × 2 = 6) Step 3: Then, multiply the ones digit 4 of the multiplicand by the tens digit 1 of the multiplier. (4 × 1 = 4) Step 4: After that, multiply the tens digit 3 of the multiplicand by the tens digit 1 of the multiplier. (3 × 1 = 3) Step 5: Finally, add the partial products. (68 + 340 = 408)
