16 can be divided into 10+6, where 10 is ten digits and 6 is one digit. So 6 in the unit is 6 1.
The relevant knowledge of this unit is as follows:
1, the unit is a basic concept in mathematics, and it is the lowest digit in the decimal representation of integers. In decimal notation, from right to left, every number has a name, and every number is the rightmost number. The main feature of the unit bit is that it is the lowest digit of an integer and can only represent numbers from 0 to 9. In decimal numbers, the number of digits increases upward from 0.
2. For example, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9. There are specific rules for the operation of units in mathematics. For example, in addition, the single digits must be added up. If it exceeds 10, it will enter one and enter ten. In subtraction, if the number of digits is not enough, one digit will be retired from the ten digits; If the number of digits is still insufficient, one will continue to retreat from the hundred digits until the number of digits is enough.
In multiplication, you only need to multiply the single digits. In the division operation, the single digits of the general quotient directly take the single digits of the dividend and divide it by the single digits of the divisor. If the division is infinite, take the integer part. In addition to basic mathematical operations, unit is also widely used in data analysis and computer science.
4. For example, in statistics, single digits are often used to represent data distribution. In computer science, the number of units is the basis of digital representation inside the computer. Unit is a basic concept in mathematics. It is the lowest digit in an integer, and has specific operation rules and application value. Understanding the concept and characteristics of unit is of great significance for learning and applying mathematics.
5. With the help of some learning tools such as sticks, let them understand "Why are there several tens on ten?" For example, put the sticks of 10 in a bundle on the left (the position of ten) and a single stick on the right (the position of one). In this way, the three sticks on the right represent three ones, and the bundle of 1 on the left represents 1 10, which together is 13.
