Can I post the text? I'll read it often. If I post it, I'll translate it for you that day. There won't be many people who can find it (post it after 22 o'clock and finish it the next day. I have an exam on September 13 and go out on September 6. I may not be able to do it these two days.)

A simple algorithm of 98 + 104 + 101 + 97 + 96 + 102 + 104 + 95

Take 100 as the standard
Original formula = 100 * 8-2 + 4 + 1-3-4 + 2 + 4-5 = 100 * 8-3 = 797

A math problem in grade three, online, etc~~~
As shown in the figure, circle O is the circumscribed circle of triangle ABC, BC is the diameter of circle O, D is the midpoint of inferior arc AC, and BD intersects AC at point E. if BC = 5 / 2, CD = √ 5 / 2, find the length of de

The current price of a TV set is 2500 yuan per set, which is 500 yuan lower than the original price. How much is the decrease? (keep one decimal before the percent sign)
Write the process down

The original price is unit one, the original price = 2500 + 500 = 3000, so the reduction is 500 / 3000, which is about 17%

If the line y = KX + B is parallel to the line y = 5-2x and passes through the point (3, - 1)
Ask for:
1) The value of K and B
2) The value of X when y = - 9

The line y = KX + B is parallel to the line y = 5-2x
K = - 2, y = - 2x + B (3, - 1)
b=5
y=-2x+5
When y = - 9, - 9 = - 2x + 5, x = 7

There are proverbs and idioms about the Yellow River

As the saying goes, "when the river goes to Wencheng County, the granary is suddenly poor"; "when the lonely cypress catches the river, the driving Department of Tang Dynasty forgets to move out." "if you don't reach the Yellow River, you will never die." "if you don't reach the Yellow River, you will never die." "if you don't reach the Yellow River, you will never turn back to the Yellow River."

In the percentage problem, is it the same for a 100 yuan commodity to reduce its price by 10% and then increase its price by 10% as for a 100 yuan commodity to increase its price by 10% and then decrease its price by 10%?
Why? If it's 100x (100X10%), is that ok

The result is the same:
First reduce the price by 10%, then increase the price by 10% = = = 100 * (1-10%) * (1 + 10%) = 90 * 1.1 = 99 (yuan)
First increase the price by 10%, then decrease the price by 10% = = = 100 * (1 + 10%) * (1-10%) = 110 * 0.9 = 99 (yuan)
It's all 99 yuan
But the meaning is different

Compare the size of the left and right products below (fill in ">", "<" or "=") 987654321 × 123456789______ 987654322×123456788．

987654321 × 123456789, = 987654321 × (123456788 + 1), = 987654321 × 123456788 + 987654321987654322 × 123456788, = (987654321 + 1) × 123456788, = 987654321 × 123456788 + 123456788, because 987654321 × 123456788 + 987654321
