What are the numbers represented by fingers?

Numbers from one to five are relatively simple. Open your hand and stretch out different numbers of fingers to represent numbers from one to five.

Six: thumb and little finger open, other fingers in the palm;

Seven: the thumb, forefinger and middle finger extend upward and converge at one point, and the rest fingers are held in the palm;

Eight: the thumb and forefinger extend at right angles to form the English letter "L";

Nine: the index finger is hooked and the other fingers are held in the palm; Ten: five fingers clench fist.

In many areas in the north, the index finger is straight, and the index finger with the middle finger crossed is ten.

And: the hand index in the gesture expressions of one, three, five, seven and nine also corresponds to odd numbers; Two, four, six, eight, and ten are also hand indexes corresponding to even numbers (ten, five fingers clench fists, and zero fingers are even numbers), so it is conceivable that the expression of the ancients is very rigorous.

Pictographic interpretation

One to five

Needless to say, from one to five, each finger represents "1" units;

Liu Heqi

At 6: 00 and 7: 00, the thumb began to represent "5" units, and for the convenience of finger expression, 6 means that the thumb and little finger are open, and 7 means that the thumb and forefinger and middle finger are close together, which is the number "7".

eight

The principle of eight is similar, the thumb means "5", and the position of the other four fingers has two explanations: one is that the development of thumb, index finger and middle finger is similar to the "eight" of Chinese characters; The other regards the thumb, middle finger, ring finger and little finger close to the palm as an additive relationship, that is, (5+3). (The former explanation may be more easily accepted by the public, and the latter explanation also has its rationality. )

nine

Nine is equivalent to (10- 1), that is, the downward bending of the index finger means that ten units are missing one unit.

ten

Ten is a fist, which looks like a stone (ten), so the homonym is ten.

zero

Number 0: The index finger and the tip of the thumb form a circle, indicating the number 0.
