Mastering Finger Multiplication

Multiplying numbers by 9 has never been easier! By utilizing the power of your fingers, you can perform calculations in a breeze. Let's dive into the step-by-step process:

Step 1: Prepare Your Hands

To begin, extend both of your hands in front of you, palms facing up. Make sure your fingers are spread apart and ready for action.

Step 2: Number Each Finger

Assign each finger a number from 1 to 10, starting from your left thumb and progressing towards your right pinky finger. This numbering system will serve as a reference during the calculation process.

Step 3: Multiply By 10

Imagine the number you want to multiply by 9. For example, let's take the number 5. To calculate 5 multiplied by 9, you'll multiply 5 by 10, which equals 50.

Step 4: Begin the Finger Calculation

Now, fold down the finger that corresponds to the number you are multiplying by 9. In this case, fold down your left pinky finger, representing the number 5.

Step 5: Count Fingers

Count the fingers on the left side of the folded finger, which is 4 in this example. This represents the tens digit in the final result.

Step 6: Count Remaining Fingers

Count the fingers on the right side of the folded finger, which is 5 in this example. This represents the ones digit in the final result.

Step 7: Combine the Results

Lastly, combine the tens and ones digits to obtain the final answer. In this case, the result is 45.
