To use this simple multiplication trick, you just need to count on your fingers and the answer will be supplied to you!
Ok, so let's say I want to work out
2 x 9
- Open your two hands and spread your fingers out, palms down.
- Start counting from the pinky finger of your left hand. Count two fingers.
- Bend the second finger down.
- Look at your hands. You should have 1 finger upright, then a gap, followed by 8 upright fingers. So the answer to 2 x 9 is 1 and 8, or 18.
Let's try again. This time we'll look at
6 x 9
Again, the steps are:
- Open your two hands and spread your fingers out, palms down.
- Start counting from the pinky finger of your left hand. Count 6 fingers.
- Bend the sixth finger down. This should be the thumb of your right hand.
- Look at your hands. You should have 5 fingers upright, then a gap, followed by 4 upright fingers. So the answer to 6 x 9 is 5 and 4, or 54.
There you go, it's as simple as that!
Another handy tip to check that you have the right answer:
IF YOU ADD THE TWO DIGITS IN YOUR RESULT, THEY SHOULD EQUAL 9!
Let's check:
2 x 9 = 18
1 + 8 = 9
6 x 9 = 54
5 + 4 = 9
These multiplication tricks are very handy when working on the 9 times tables, but remember that they only work up to 9 x 10.
