You're trapped on a desert island and you need to do some multiplications for crops and stuff, but don't have a calculator. What to do? Don't worry, there is always Japanese Stick Multiplication!
Example 1: Using Japanese stick multiplication, show
$$23\times 14=322$$
Draw the sticks according to the numbers as shown and separate into different groups as shown with the lines, working your way outside in, so start with the two end groups.
Add up the intersection points in each group. The are 3 separate areas here, separated by the 2 lines.
Write down these numbers along one line as shown below.
Starting with the number on the far right, 12.
Use the left digit in each number.
The right digit carries over to the next one on the left.
$$412\times 1462=602 \,344$$
