The conditions for math problems are all set by man5

Mathematics is originally about calculation and reasoning, improve your logical thinking ability, evaluate your analytical ability, the topic itself is not a scientific research project, may not be very rigorous, but the only requirement here is the answer and calculation process, one is to consider your solution ideas and examine your calculation accuracy, about the answer you said is very coincidental, this is a mathematical law, generally you just do a question right, its answer is generally very simple (more than 90%), if the answer is too complex then you need to look again, If your answer can be found with a few elements of this body, then you can try, using the answer to reverse the formula is also a way to enrich the way to solve the problem, but it depends on your thinking ability, whether you can make sense of your backward formula, you have to ask why, the answer is that this is mathematics, boring and full of coincidences.

I was shocked when I first saw your question: which school is so open, math problems are also out of the NBA category, is it to count the number of rebounds?

That's to develop your way of thinking and approach.

Publication is only a means, not an end. The ultimate goal is for you to master the methods of analyzing and solving problems. This is the foundation of education. Coincidence or not coincidence is secondary, and coincidence is because it saves you time in calculations. Look at the essence through the phenomenon!

Originally, there was the answer first, and then there was the question, and the person who wrote the answer first came and then "created" the question, so we always felt very coincidental.

Yes the answer (Iverson) is that coincidental.

So how do you want to educate?

1) The first number is thought, the second number on the right is x+1, the third number on the bottom is x+7, and the fourth number in the lower right corner is x+8.

2) x+(x+1) hail collapse return + (x+7) + (x+8) = 416, the solution is x=100

3) is the same as two, 4*x+16=324, and the solution is x=77

Hello: 23 questions.

cd=4-3/2=5/2

If you are satisfied, remember to adopt it!

Ask for good reviews! * Hee-hee-hee ......

23. cd=

24(1) From the question, it can be seen that BF=CD, angle B=angle BCA, BC=AC (SAS) are congruent.

2) From (1) to get ad=cf, the triangle ade is equilateral, then ad=de so ed=cf, because the triangle ade and abc are equilateral, d is the midpoint of the triangle line abc, so the angle adb is 90 degrees, from the congruent angle adb=angle bfc=90 degrees, angle b=60 degrees, angle eda=60 degrees, so the angle edb=angle fcb=30 degrees, so ed parallel fc, so get the parallelogram cdef

They are all written as 11 times, and the 55th power of 2 is equal to the 11th power of 2 to the 5th power. That's it. The third one doesn't know what to say, hehe, don't say it, of course give it to me.
