Easy, just get a multiplacation chart. And get two numbers, put your finger on the first number in the chart, and put another finger from your other hand on the second number. Move your finger straight until you see that your finger has landed under the first number. For a instance,
4 X 8.
Put the first finger on the 4, and slide it down until you see that the finger is in the 8s section. You then have a answer.
