Subtraction is addition. What?

Question 1: The inverse operation of subtraction, what does addition mean? Addition is the operation of combining two numbers into one number. Such as 5+3=8

Subtraction is an operation to find the other addend by knowing the sum of two addends and one of them. For example, 8-5=3 or 8-3=5.

Addition and subtraction are reciprocal operations.

Question 2: What is the relationship between addition and subtraction (1) The operation of combining two addends into one number is called addition.

(2) Given the sum of two addends and one of them, the operation of finding the other addend is called subtraction. Subtraction is the inverse of addition.

(3) Using the addition and subtraction relation, we can check whether the result of the addition and subtraction formula is correct, and we can also find out the unknown in the addition and subtraction formula.

Question 3: What is the quantitative relationship between addition and subtraction? The quantitative relationship between addition and subtraction is as follows:

Negative-negative = difference

Difference = minuend-minuend

Subtraction-Difference = Subtraction

Subtraction = minuend-difference

Difference+Minus = Minus

Subtraction+difference = minuend

Subtraction = difference+subtraction

Negative = negative+difference

Appendix+Appendix = Sum

Appendix = Sum-Another Addendum

Addition is one of the four basic operations, which refers to the calculation of combining two or more numbers and quantities into one number and quantity. The symbol of addition is the plus sign "+". Connect items with a plus sign when adding. Add and after the equal sign "=". For example, if the sum of 1, 2 and 3 is 6, it is written as U 1+2+3=6.

Subtraction is one of the four operations, and the operation of subtracting one quantity from another is called subtraction; Given the sum of two addends and one of them, the operation of finding the other addend is called subtraction. The symbol of subtraction is "-",which is pronounced as negative sign. Used to calculate decrement.

Question 4: Is the difference addition or subtraction? Difference refers to the difference between two numbers or one number compared with other numbers, so it should be subtraction.

Question 5: It is the same whether there is addition or subtraction.

How to calculate simply?

The habit is to count the front first, then the back.

Question 6: What is addition, subtraction, multiplication and division?

The operation of combining two numbers into one number, the operation of combining two decimals into one decimal, and the operation of combining two fractions into one fractional.

subtraction

The operation of finding the other addend by knowing two addends and one of them.

Question 7: What is cost plus? What is cost subtraction In MSO system, cost addition and subtraction is an unavoidable link. As a business owner, you must learn the thinking mode of "cost addition and subtraction" and apply "cost addition and subtraction" to all aspects of your business operation. In this way, your enterprise will achieve a healthy and rapid development.

From our traditional thinking, the cost control of enterprises is nothing more than saving the construction cost and operation cost of enterprises, and cost saving means improving the profits of enterprises.

But cost control not only means saving, but also means "focusing on increasing" Most business owners see the former and ignore the latter.

Only by mastering the "cost control" can we first decompose the cost into "subtraction" and "addition" and then use them comprehensively to achieve the best effect.

Cost control often determines the success or failure of a company. This is definitely not sensational. For many enterprises on the verge of bankruptcy or in the bottleneck of development, "cost addition and subtraction" may save your enterprise immediately.

We take the 7-day economy hotel chain as an example to analyze the law of "cost addition and subtraction". Any enterprise can use this method to control costs. Most importantly, you must learn this way of thinking.

In the usual star-rated hotels, we can see that the hotel provides many very comfortable facilities for customers. For example: conference room, Chinese and western restaurants, mini-bar, swimming pool, red carpet, luxurious decoration ... Undeniably, these facilities make guests feel very elegant and enjoy.

However, within seven days, the hotel cut off all these equipment. Because these are all construction costs, and will continue to generate operating costs. For 7 days, the hotel only kept the core facilities such as bed, private bathroom, TV, telephone, shower, broadband service and writing desk.

In addition, the 7-day hotel also reduced the room area, reducing the common 20 square meters of other budget hotels to 18 square meters; Making windows smaller can save construction costs and maintenance costs; Optimize the indoor lighting structure, realize effective lighting, and save energy at the same time ... these all effectively save costs.

In terms of cost saving, 7 days hotel has a detail that all business owners should think about: at first, it takes 50 minutes for the waiter to clean each room; In order to improve efficiency, they specially designed a set of scientific cleaning procedures, requiring waiters to clean in strict accordance with the procedures. As a result, the time was reduced to 25 minutes. The cost of time is also strictly calculated into the cost system of 7-day hotel.

Herb, president of Southwest Airlines? Keller once said, "You can play a joke on the stewardess on her birthday, but I'm afraid you can't throw ribbons at her, because it will lead the cleaning staff to spend more time cleaning and increase the cost."

It is the demanding demand for cost saving that makes 7 Days Hotel one of the few profitable enterprises in China's budget hotels. It is precisely because of this cost-saving attitude that Southwest Airlines has become the only one of the five most famous airlines in the United States that has not gone bankrupt and continues to make high-speed profits.

Therefore, for the cost control of enterprises, first of all, you should learn to "subtract", mercilessly cut off many seemingly necessary things in the whole industry, and pay attention to the scientific and concise nature of every process and detail in the operation process.

Now let's see how the 7-day hotel "increases" the cost.

7 days hotel deeply understands a truth: cost control must focus on meeting the core needs of customers.

What are the core needs of customers staying in a 7-day hotel? It's simple: have a good sleep and a good bath.

I saw a description about the cost addition of 7-day hotel: "The hardware facilities of 7-day hotel are simpler than those of ordinary hotels, but in terms of the core needs of beds and toilets, the investment has been increased: the big bed is widened to 1.8 meters, and the five-star hotel-class mattress is matched with pure white cotton bedding with the highest intuitive cleanliness and strong ventilation function; In order to let customers take a comfortable hot bath, 7 Days Hotel specially developed a patented integral bathroom design to make the shower room more quality. Shower setting ensures that the water flow heats up at a speed of 65,438+00 seconds, making bathing more comfortable. In order to improve customers' sleeping environment, 7 Days Hotel added a double-layer sound insulation glass to the small window of the guest room, and also introduced a specially customized soundproof door to minimize noise and create a quieter and more comfortable guest room space. "

The application of "cost addition and subtraction" is not simply to control costs, nor to weaken the customer experience. & gt
