Do you have a summary?
thank you.

In Baidu library collection, where the very detailed

Put a pile of apples into some boxes. If each box contains 8 apples, there are 12 apples left. If each box contains 9 apples, there are still 3 apples left to fill the last box. The total number of apples is 3______ An apple, yes______ It's a box

(12 + 3) △ 9-8, = 15 △ 1, = 15 (pieces), 15 × 8 + 12, = 120 + 12, = 132 (pieces); answer: there are 132 apples and 15 boxes

20000 square decimeters equals () square decimeters

20000 square decimeters
=20000÷10000
=2 square meters

A cuboid glass container, measuring 2 mm in length and width, is poured into the container with 5.5 L water, and then an apple is put into the water. At this time, the water depth in the container is 15 cm. What is the volume of the apple?

First calculate the height of 5.5L water poured into the container, then use 15 to reduce the height of water is the height of water discharged from the volume of the apple, and then calculate the volume of the apple
Or: after putting in the apple, the height of the volume of water and apple is 15, count the volume of water and apple, then subtract the volume of water
When you encounter problems, you have to think for yourself. It's easy to understand to draw pictures

1. The perimeter of a square is 9.48 meters. What's its side length? Side length = perimeter △ 4 = 9.48 △ 4 = 2.37 meters. A: its side length is 2.37 meters. 2. A car can travel 12.8 kilometers in 8 minutes, and a bus can travel 14.4 kilometers in 12 minutes

12m3, 80m3 = () cubic decimeter = () liter, 3250ml = () cubic decimeter () cubic centimeter
If you double the length, width and height of a cuboid, the surface area will be () and the volume will be (). If the edge length of a cube is reduced to 1 / 3 of the original, the surface area will be (), and the volume will be ().

12 cubic meters 80 cubic decimeters = (12080) cubic decimeters = (12080) liters,
3250 ml = (3) cubic decimeter (250) cubic centimeter

Addition and subtraction of integral
1. Students do a problem, (2x & sup2; - 3x & sup2; - 2XY & sup2;) - (X & sup3; - 2XY & sup2; + Y & sup3;) + (- X & sup3; + 3x & sup2; Y-Y & sup3;), where x = & frac12; (half) y = - 1, Xiao Ming copied x as - & frac12; (negative half), but the result is the same, why?
2. A represents a two digit number, B represents a three digit number, AB is arranged into a five digit number, M1, Ba is arranged into a five digit number, M2?
3. Given | a + B-2 | + (AB + 3 & sup2;) = 0, find the value of 2 [AB + (- 3a)] - 3 (2Ab AB)
Who knows the solution and the result?
Correct question 3 to read:
Given | a + B-2 | + (AB + 3) & sup2; = 0, find the value of 2 [AB + (- 3a)] - 3 (2Ab AB)
We didn't answer completely. We'll have it tomorrow morning. (October 23)

Question 1: I feel that the first polynomial has a problem, X2 repeat;
Second question:
Let a = 10 * n + m (n > 0, M > = 0)
b=100*p+10*q+r (p>0,q>=0,r>=0)
Where N, m, P, Q and R are integers from 0 to 9;
M1=1000*a+b
=10000*n+1000*m+100*p+10*q+r
M2=100*b+a
=10000*p+1000*q+100*r+10*n+m
The subtraction of the two formulas is as follows:
M1-M2=9990*n+999*m-9900*p-990*q-99*r
=9*(1110*n+111*m-1100*p-110*q-11*r)
Since the formula in brackets must be an integer, m1-m2 is a multiple of 9. Am I clear?
Third question:
The left side of the equation should be | a + B-2 | + (AB + 3) ^ 2 = 0
The absolute value and the square number are not negative, the sum is zero, so they are all zero
A + B = 2 ab = - 3 the rest of the work is up to you

-The general formula of 3. - 6. - 9. - 12

-The general term formula of 3. - 6. - 9. - 12 is an = - 3N (n is a positive integer) and the sign is negative. 3 = 3 × 16 = 3 × 29 = 3 × 312 = 3 × 4. Therefore, the general term formula of an = 3N1, - 3.5. - 7 is an = (- 1) & #; - & #; × (2n-1) (n is a positive integer) and the sign is one positive and one negative. Then (- 1) & #; - & #; can be used to express 1 =
