Unlock the Power of Your Fingers: Mastering Multiplication with Your Hands

Forget calculators! Believe it or not, your own two hands can become powerful tools for multiplication, especially for those tricky times tables. This method, while not universally applicable to all numbers, provides a fantastic, visual, and memorable way to grasp the concept of multiplication, particularly with numbers between 6 and 10. This article will guide you through the fascinating world of finger multiplication, step-by-step, making learning math interactive and fun. Let’s dive in!

Why Use Finger Multiplication?

Before we jump into the how, let’s understand why finger multiplication is a valuable skill:

• Visual Learning: It engages your visual and kinesthetic senses, making the learning process more concrete and easier to remember.
• Mental Math Practice: It encourages mental calculation and improves your number sense.
• No Tools Required: You always have your hands with you, making it a handy tool on the go.
• Boosting Confidence: Successfully multiplying with your fingers can boost confidence in mathematical abilities.
• A Fun Alternative: It makes learning multiplication less tedious and more engaging, especially for children.

The Basics: Number Representation

The fundamental principle of finger multiplication is representing numbers using your fingers. Each finger represents a value, and the specific method we’ll discuss focuses on multiplying numbers from 6 to 10. Here’s how we assign numbers to our fingers:

For each hand:

• Thumb: Represents the number 6
• Index finger: Represents the number 7
• Middle finger: Represents the number 8
• Ring finger: Represents the number 9
• Little finger: Represents the number 10

Important Note: In this system, the numbers on the same finger on each hand will be the same. So, your right thumb will be 6, and your left thumb will also be 6.

The Technique: Step-by-Step Guide

Now, let’s get to the exciting part – the multiplication process! We’ll illustrate this with a few examples.

Example 1: 7 x 8

Here’s how to multiply 7 by 8 using your fingers:

Step 1: Position Your Hands

Start by holding your hands in front of you. On your left hand, touch the index finger (7) to the index finger on your right hand (7). Now count the number of fingers below the two touch fingers. Since you have two fingers up on your left hand which corresponds to 7 and 3 fingers on your right hand which corresponds to 8, you will connect index to middle finger respectively.

Step 2: Count the Fingers that Touch and Below

On both hands, count all of the fingers that are below the fingers that are touching and the fingers that are touching. In this case, you are connecting the index finger (7) on your left hand to the middle finger (8) on your right hand, therefore you will count the touching fingers of both hands plus any fingers below. On your left hand, the index and the thumb are below or touching. On your right hand the middle finger and the index finger are below or touching. This makes a total of 5 touching or below fingers ( 2 left hand and 3 right hand) These counted fingers represent the tens digit in our final answer, so, in this case, we have 5 tens, or 50.

Step 3: Multiply the Fingers Above

Now, count the number of fingers that are above the touching fingers on your left hand and on your right hand. On your left hand, there are 3 fingers above the touching finger (7). On your right hand there are 2 fingers above the touching finger (8). Multiply these numbers together, i.e., 3 x 2 = 6.

Step 4: Add the Results

Finally, add the result from Step 2 (50) to the result from Step 3 (6) : 50 + 6 = 56. Therefore, 7 x 8 = 56.

Example 2: 6 x 9

Let’s try another example with 6 multiplied by 9:

Step 1: Position Your Hands

On your left hand, touch the thumb (6). On your right hand, touch the ring finger (9).

Step 2: Count the Fingers that Touch and Below

Count the fingers that are touching and those below them. On your left hand, the thumb is touching which gives 1 finger. On your right hand the ring, middle, and index fingers, and thumb are touching or below which gives 4 fingers. Total count of 5 fingers (1 left and 4 right). This gives us a 5 in the tens place, meaning 50.

Step 3: Multiply the Fingers Above

Count the number of fingers that are above the touching fingers on your left hand and on your right hand. On your left hand, there are 4 fingers above the thumb (6). On your right hand, there is 1 finger above the ring finger (9). Multiply these numbers together: 4 x 1 = 4.

Step 4: Add the Results

Add the result from Step 2 (50) to the result from Step 3 (4): 50 + 4 = 54. Therefore, 6 x 9 = 54.

Example 3: 6 x 6

Now lets try an example with 6 multiplied by 6:

Step 1: Position Your Hands

On your left hand, touch the thumb (6). On your right hand, touch the thumb (6).

Step 2: Count the Fingers that Touch and Below

Count the fingers that are touching and those below them. On your left hand, the thumb is touching which gives 1 finger. On your right hand the thumb is touching which gives 1 finger. Total count of 2 fingers (1 left and 1 right). This gives us a 2 in the tens place, meaning 20.

Step 3: Multiply the Fingers Above

Count the number of fingers that are above the touching fingers on your left hand and on your right hand. On your left hand, there are 4 fingers above the thumb (6). On your right hand, there are 4 fingers above the thumb (6). Multiply these numbers together: 4 x 4 = 16.

Step 4: Add the Results

Add the result from Step 2 (20) to the result from Step 3 (16): 20 + 16 = 36. Therefore, 6 x 6 = 36.

Practice Makes Perfect

Like any new skill, finger multiplication requires practice. The more you use it, the faster and more comfortable you’ll become. Start with smaller multiplications and gradually progress to larger numbers. Here are some practice problems you can use:
