1, divisor is an integer fractional division calculation rule: divisor is an integer fractional division, which is removed according to the integer division rule, and the decimal point of quotient should be aligned with the decimal point of dividend; If there is a remainder at the end of the dividend, add 0 after the remainder and continue the division.
2. Divisor is a decimal division calculation rule: divisor is a decimal division, first move the decimal point of divisor to make it an integer; The decimal point of the divisor is shifted to the right by several digits, and the decimal point of the dividend is also shifted to the right by several digits (if the digits are not enough, the dividend is supplemented by 0 at the end, and then calculated by fractional division with the divisor as an integer.
3. The divisor of quotient: according to the number of decimal places to be reserved, decide how many decimal places to divide by quotient, and then reserve a certain number of decimal places according to rounding method to find the divisor of quotient. For example, if you want to keep one decimal place, you can stop dividing the quotient to the second decimal place; If two decimal places are needed, the quotient should stop at the third decimal place, and so on.
The benefits of mind mapping
1. Integrating information: Mind mapping can help people integrate a large amount of information, present scattered knowledge points or ideas in a graphical way, and make complex information clearer and easier to understand.
2. Stimulate association: By drawing mind maps, people can freely associate and extend various ideas, thus generating more creativity and problem-solving methods. This helps to open up thinking and promote innovation.
3. Strengthen memory: Mind mapping combines various elements such as words, colors and graphics, and the combination of these elements can help memory. Compared with traditional word notes, mind maps are easier to remember and understand.
4. Improve efficiency: Mind mapping displays information in a branched way, which can make people see the relationship between various information points at a glance, thus helping people to sort out their ideas more quickly and improve the efficiency of work and study.
