Explanation:

32 x 3 = ?

Multiply the ones: 3 x 2 = 6

Multiply the tens: 3 x 3 = 9

32 x 3 = 96

96 x 8 = ?

MULTIPLY ONES: 6 x 8 = 48

WRITE AND CARRY: Write the "8" and carry the "4"

MULTIPLY TENS: 8 x 9 = 72

ADD: Add the carried amount. 72 + 4 = 76

WRITE: Write down the "76"

Answer: 96 x 8 = 768

This works for however many digits you need to multiply.
