MindMap Gallery Summary of four calculation knowledge points
This mind map mainly introduces four basic operations in mathematics: addition, subtraction, multiplication and division, and elaborates in detail their basic definitions, properties, applications in daily life, and operation rules.
Edited at 2025-02-16 11:46:47This is a mind map about the annual work plan of the three pillars of human resources. The main contents include: strategic human resources planning, talent recruitment and allocation, employee performance management, employee training and development, employee relationships and communication, employee welfare and care, human resources information system construction, regulatory compliance and risk management, and organizational culture construction.
This is a mind map for the diagnosis and treatment of acute cerebral hemorrhage in patients with hemodialysis. The annual incidence of acute cerebral hemorrhage in patients with hemodialysis is (3.0~10.3)/1000, and the main cause is hypertension. Compared with non-dialysis patients, the most common bleeding site is the basal ganglia area, accounting for 50% to 80%; but the bleeding volume is large and the prognosis is poor, and the mortality rate is 27% to 83%. Especially for patients with hematoma >50ml, hematoma enlarged or ventricular hemorrhage on the second day after onset, the prognosis is very poor.
The logic is clear and the content is rich, covering many aspects of the information technology field. Provides a clear framework and guidance for learning and improving information technology capabilities.

nature
Exchange law
Change the order of the additions, the result remains unchanged
Combination law
Change the combination method of add-ons, the result remains unchanged
application
Merger and accumulation in daily life
Calculation of income in finance
Subtraction operation
definition
The process of removing another number from one number
nature
Not satisfied with the law of exchange and bonding
application
Separation and reduction in daily life
Expenditure calculation in finance
Multiplication operation
definition
The process of repeatedly adding a number to itself several times
nature
Exchange law
Change the order of factors, the result remains unchanged
Combination law
Change the combination method of factors, the result remains unchanged
Distribution Law
Multiplication can be assigned to addition or subtraction
application
Repetition counting and area calculation in daily life
Profit calculation in finance
Division operation
definition
The process of dividing a number into several equal parts
nature
Not satisfied with the law of exchange and bonding
Divided by 1 equals the original number, and divided by 1 equals the original number
application
Equal distribution and division in daily life
Cost analysis in finance
Operation order
Basic Rules
Multiply and divide first and then add or subtract
Operations in brackets are preferred
Special circumstances
When multiplication and division occur at the same time, calculate it from left to right.
When addition and subtraction occur at the same time, calculate from left to right.
Operator symbols
Plus sign ( )
Representing addition operation
Minus sign (-)
Represents subtraction operation
Multiplication sign (× or ·)
Representing multiplication operation
Diction sign (÷ or /)
Representation of division operation
Operational law
Additive operation law
Exchange law
a b = b a
Combination law
(a b) c = a (b c)
Multiplication law
Exchange law
a × b = b × a
Combination law
(a × b) × c = a × (b × c)
Distribution Law
a × (b c) = a × b a × c
