Binary Count Fingers

Binary Count Fingers is a method in which one or more hands are used to count and display binary numbers on our fingers.

Counting Various Numbers by Hand Gestures for Numbers

• The basic idea of Hand Gestures for Numbers is finger math addition where fingers are added to display the numbers.

• Using the fingers of a single hand, we can count from 0 to 31.

• By using fingers from both hands we can count from 0 to 1023.

• Using fingers from both hands and toes from both feet we can count from 0 to 1,048,575.

Finger Math Addition

I have four fingers and a thumb in my right hand, so using this let us count from numbers 1 to 31. Here while counting the numbers we will use addition with fingers. That is to show the consecutive numbers we will add the fingers.

• When no fingers up give us zero.

To count after 32 we need fingers from both hands.

Counting Higher Numbers

When we are using hand gestures for numbers one hand is enough to count numbers from 0-31. But to count above 31 we need fingers from both of our hands. When we are using both hands to represent numbers we will use finger math addition i.e we will represent one number in the right hand and another number in the left hand and later we will add the numbers to get the final answer.

Ex: If we have to represent 34 using our fingers we will make use of all 10 fingers from both of our hands.

So here first we will make use of the right hand as we have calculated basic numbers from 0-31. So we will represent 2 in the right hand which is as follows.

Now on the left hand, we will represent 32.

So now when we add these two we will get the number 34 which is represented by using both hands.

So this diagram shows the binary count finger of 34.

Problems on Binary Count Fingers

1. A girl counted in the following way: I have four fingers and a thumb in my right hand and thumb, middle finger and fourth finger are up. So what is the number?

Ans: When thumb, middle finger and fourth finger are up we will get the number thirteen (13) which is shown below.

2. A girl counted in the following way: I have four fingers and a thumb in my right hand and little finger, fourth finger, middle finger and index fingers. So what is the number the girl counting in her hand.

Ans: When the little finger, fourth finger, middle finger and index fingers are up we will get the number thirty (30) which is shown in the below picture.

Conclusion

Gestures are a form of nonverbal communication in which the visible actions of the body are used to convey important messages, either together or in the place of words spoken in parallel. The movement of hands, face, and other body components includes gestures.

So hand gestures for numbers are useful when speech communication is not possible. The binary count fingers will also help students to understand the basics of counting numbers easily.
