Long Multiplication
Long Multiplication is a special method for multiplying larger numbers.
It is a way to multiply numbers larger than 10 that only needs your knowledge of the ten times Multiplication Table.
Let us say we want to multiply
612 × 24
When we multiply 612 × 20 we only need to multiply 612 × 2 and place the result one column over (so it is the same as multiplying by 20).

Let us say we want to multiply
612 × 24
- First we multiply 612 × 4 (=2,448),
- then we multiply 612 × 20 (=12,240),
- and last we add them together (2,448 + 12,240 = 14,688).
