The questions of elementary school students are too rebellious, who will help me calculate.

Landlord, let me analyze it this way, for 9, how can there be = 9? Unless it's 3 3, all combinations are impossible, and 9 is not. So 9 can only appear 9= in this case, but if you try all the combinations with 9, you can only use 9=72 in these three cases, first 5 9 = 45 can not be achieved with two 5s, so to use all 9 you must use one of the last two groups twice, but obviously it is impossible, because if 6 9 = 54 is used twice, 5 is only one, if 8 9 = 72 is used twice, 7 is only one, so 9 is not used anyway.

I remember having a similar problem before, it seemed to be a card, and 9 was reversed to 6.

I don't know if my analysis is rigorous, please make it clear to the landlord.

There should be no solution to this problem, and I analyze it like this:

A total of 16 numbers, 4 are used for each question, and the form of each question is: ? x？=？？

Important focus on the number 9

The number 9 can only be used for the answer to 49, i.e. 7x7=49, but there is only 1 7 in the number, so it does not work.

The number 9 is used as a multiplier, and there can only be two programs:

5x9=45

6x9=54

8x9=72

But there is only 1 5, and it is not possible to complete the program of 3 9s.

9x8=72

6x8=48

7x6=42

That's all I can think about.

Woooooooo Can it be repeated? If you can, 9x8=72

6x8=48

7x6=42

I think if it weren't for the card, there should be no solution, and the 9 becomes the 6, and there is basically no need to ask for help.

I'm also in the first year of junior high school, math, in fact, I'm not bad at math, but I also came from a bad student, so don't be discouraged, in fact, math is to do more questions, and if you master the question type, it will naturally not be difficult. There is no need to buy any teaching materials, as long as you listen carefully in class, answer actively, and practice more, class time is the most precious, and you can get twice the result with half the effort with the guidance of the teacher. If you encounter a problem that you don't understand, you must take the initiative to ask your classmates or teachers, and occasionally do a few difficult math problems, which will also help your math, this is all my experience, I wish you success!!

Adopt it, no one can say that there is no hope.

A seemingly simple elementary school arithmetic problem is always answered correctly. If you don't believe it, try it!!

One person took a 100-dollar bill to the store and bought a 25-yuan item, and the shopkeeper took the 100-dollar bill to the vendor next door to exchange it for 100 yuan and recovered the person's 75 yuan because he had no change. The man walked away with $25 and $75 in change. After a while, the vendor next door approached the shopkeeper and said that the 100-yuan bill that the shopkeeper had just exchanged for change was a counterfeit.

The shopkeeper took a closer look, and sure enough, it was a counterfeit banknote. The shopkeeper had no choice but to find a real 100-dollar bill for the vendor.

Q: How much money did the owner lose in the whole process?

Note: Counterfeit banknotes cannot be used, which is equivalent to a blank piece of paper. Goods are also counted as money. And the calculation of the goods is 25 yuan, regardless of the cost and profit tax.

It's really a simple question haha I can't get the right answer haha classmate, don't be so funny, at least give us the question.

The shopkeeper lost 100 yuan, and before the shopkeeper compensated, he regarded 100 yuan as genuine banknotes, and finally compensated 100 yuan, so he lost 100 yuan.

Let Xiao Ming's age = x, then Dad's age = 6x

As can be seen from the title, 6x+4=4*(x+4).

6x+4=4x+16

2x=12x=6Answer: Xiao Ming is 6 years old this year (Dad is 36 years old this year).

Solution: Set Xiao Ming four years ago. The column equation is 6x+4=4 (x+4). The result was 6 years old.

Let's say Xiao Ming is x years old this year, and Dad is 6x years old.

4（x+4)=6x+4

12=2xx=6Xiao Ming is 6 years old this year.

If the column equation lets Xiao Ming's age be x, then Xiao Ming's father's age is 6x, (x+4)*4=6x+4 and the solution is x=6

It's very simple, 4x6=24, Xiao Ming is 24 years old this year.

Your question is not complete: it should be a person who took a 100-yuan bill to the store and bought something for 25 yuan, the cost price of the commodity is 23 yuan, and the shopkeeper took this 100-yuan bill to the small vendor next door for 100 yuan change, and then found 75 yuan for him, and then the vendor next door came over and said that the 100 yuan was fake, and then the shopkeeper gave him 100 yuan, and asked the shopkeeper how much money he lost?

The cost of goods is 23 + change 75 + 100 = 198 to the small vendor

Loss = shopkeeper goods + recovery of change + compensation to the hawker You can see it

The shopkeeper lost 25 yuan of things, plus 75 yuan, and 100 yuan for the shopkeeper, which should be 175 yuan plus 25 yuan.

Fill in 16 58 18 36 clockwise from top to bottom

Reason 16<58 58>18 18<36 36>16 36<58 16<18

After answering, please check out.

Capital A: 40000 + 2870 = 42870

Capital B: 40,000

Total profit equalization: (105000-42870-40000) 2=11065

A: 11065 + 42870 = 53935

B: 40000 + 11065 = 51065
