Explanation:

1.

Step1: Multiply units digit: \(6\times4 = 24\), write 4, carry 2.

Step2: Multiply tens digit: \(0\times4 + 2 = 2\), write 2.

Step3: Multiply hundreds digit: \(8\times4 = 32\), write 32.

\(806\times4 = 3224\)

2.

Step1: Units: \(5\times8 = 40\), write 0, carry 4.

Step2: Tens: \(3\times8 + 4 = 28\), write 8, carry 2.

Step3: Hundreds: \(3\times8 + 2 = 26\), write 26.

\(335\times8 = 2680\)

3.

Step1: Units: \(6\times4 = 24\), write 4, carry 2.

Step2: Tens: \(9\times4 + 2 = 38\), write 8, carry 3.

Step3: Hundreds: \(8\times4 + 3 = 35\), write 35.

\(896\times4 = 3584\)
