2222 * 5556 + 8888 * 1111 (simple calculation, answer 1000 fortune)
abc13925837013 ,
2222×5556＋8888×1111
＝2222×5556＋2222×4×1111
＝2222×5556＋2222×4444
＝2222×（5556＋4444）
＝2222×10000
＝22220000

1. Xiao Gang has read 65% of a story book, 45 pages more than the rest. How many pages is there in this book?
1. How to express "pain" with "disease"
2. How to express "hate" with "disease"
45 divided by (65% - 45%) = 225 (pages)

2. Hatred of evil
If the equation x & # 178; + 4ax-4a + 3 = 0 has real roots, then we can get 16A & # 178; - 4 (3-4A) > = 0. How can we find the solution of this inequality
16a^2+16a-12>=o
Dissolve (divide each item by 16): A ^ 2 + A-3 / 4 > = 0
(a+3/2)(a-1/2)>=0
The result is: a > = 1 / 2 or a
Li Li usually takes only 20 minutes to go from home to school by bike. As there are 2 kilometers of roads being repaired on the way, she has to walk by cart, which is 2 / 3 slower than cycling
It took 36 minutes to get to school. How many kilometers did Li Li's family get to school
Usually 20 minutes to complete the journey, every minute to walk 1 / 20 of this distance, cart walking is 2 / 3 slower than cycling, then the speed of cart walking is 1-2 / 3 = 1 / 3 of cycling speed, cart walking every minute can walk 1 / 20 × 1 / 3 = 1 / 60 of this road, it takes 36-20 = 16 minutes more than the original, 2 km distance if
How much does a 4mm iron plate weigh per meter
The density of iron is revised to 7850kg / m3. The weight of steel bar per meter is to take the steel bar as a cylinder and calculate the volume of one meter multiplied by the density, which is the weight per meter. People who often make budget can recite the weight per meter. You can calculate the weight like steel bar
For example, the weight per meter of steel bar with diameter of 10 is 0.617kg. Remember this and calculate the weight per meter of other diameters according to the following method
The pithy formula is that the diameter of steel bar is multiplied by itself, and the unit centimeter should be noted clearly. Multiplying by 0.617 is the weight of steel bar per meter
For example, if the diameter of 16mm steel bar becomes centimeter, it will be 1.6. If you multiply it by 1.6, it will be self multiplication. If you multiply it by 0.617, you can calculate that the diameter of 16mm steel bar is 1.58kg per meter
The other algorithms are the same
The speed of a car is 56, which is equal to that of a bus. It is known that a car travels 120 kilometers per hour and a bus travels how many kilometers per hour?
120 × 56 = 100 (km); answer: buses travel 100 km per hour
