24 plus 24 99. Short? 10

Easy calculation, 24+24 99.

Simple calculation idea: If we do simple calculation, we can use the distributive property of multiplication operation or the properties and laws of associative law or division operation to calculate, and get the effect of our simple calculation. When we do this question, we can try to ask 24 directly, and then calculate the content in parentheses, so that we can get the answer, which will be easier.

The detailed simple calculation process is as follows, 24+24 99

Therefore, through the simple calculation process above, the answer is 2400.

Extended information: Problem solving ideas: When calculating the vertical calculation multiplication operation, first multiply the first digit of one digit by another digit to get a one-step answer.

Then multiply the low to the high digit by another digit to get a few steps of the answer. Finally, add up all the answers you get to get the final answer.

Step 1: 1 24 = 24

Step 2: On the basis of the answer in the first step, multiply by 100 to get 2400 So, you can use the multiplication operation of vertical calculation to get the answer is 2400.

Analysis of the process of clever calculations 24+24 99

Solution: Four rules of operation (calculated in order, multiplication and division first, then addition and subtraction, parentheses are counted first, and power is calculated first), that is, the off-form operation (recursive equality calculation) needs to be carried out under the premise of this principle. Problem solving process:

Extended data - vertical calculation - calculation process: first align the last digit of the two multipliers, then use the second multiplier respectively, multiply a multiplier for each number from the last digit in turn, and finally add up the calculated result to be the product, if the multiplier is a decimal place, it can be expanded by the corresponding multiple, and finally the product is reduced by the corresponding multiple;

Problem solving process: Step 1: 4 100=400

Step 2: 2 100 = 2000

Based on the above calculations, the sum is 2400

This question can be prevented.

Build a habit. Good study habits are the key to achieving good results, in life, to guide children to develop regular preview, review, do exercises, check, correct, compile a set of wrong questions and other good study habits, once the habit is formed, it will have a long-term impact on the future learning path.

to facilitate escrow. Parents and friends should learn to use more supervision instead of discipline, so that children feel that learning is a matter of their own ideas, not forced by parents and schools, so that children will be more motivated to learn.

Communicate with teachers.

Parents should communicate more with teachers, after all, there will be some differences between the child's appearance at home and at school, learn to understand more about the different sides of the child, and keep abreast of the child's learning dynamics, at the same time, to maintain a good relationship with the teacher, try to fight for a better seat for their child and the next table, this should be understood by everyone.

Extracurricular tutoring. If the child feels more difficult to learn, many knowledge points can not be digested in time, and the academic performance has dropped significantly, then it is necessary to find a tutor for the child, preferably a one-to-one professional tutor to help the child solve questions and answer doubts, and digest and absorb the day's homework in time, so that learning can reduce stumbling blocks.

Enter it into the computer, and you can calculate it quickly and easily.

Simple calculation is a special kind of calculation, which uses the laws of operation and the basic properties of numbers, so as to make the calculation easy, so that a very complex formula becomes easy to calculate the number.

The most common method used in simple calculations is the multiplicative distributive property. The multiplicative distributive property refers to ax(b+c) = axb+axc, where a, b, c are arbitrary real numbers. Conversely, AXB+AXC=AX(B+C) is called the inverse of the multiplicative distributive law (also known as extracting the common divisor), especially when a and b complement each other, this method is more useful.

There are also times when the associative property of addition is used, such as a+b+c, where b and c are complements to each other, so you can combine b and c and multiply it with a. If the + in the above equation is changed to x, it can also be easily calculated by using the associative property of multiplication.

The associative law of multiplication is also a method of doing simple operations, which is expressed by letters as (a b) c = a (b c), and its definition (method) is: multiply three numbers, first multiply the first two numbers, and then multiply the third number; Or multiply the last two numbers first, and then multiply them with the first number, and the product remains the same. It can change the order of operations in multiplication operations, and the multiplication law is not used very much in daily life, mainly in some more complex operations to play a simple role.

24+24 6 Divide first and then add.

This doesn't need to be simply calculated, the answer can be known at a glance. 24+24÷6＝24+4＝28

240 9 + 24 How Tong Ji carries the number of fronts.

240 (10-1) +24

The word "Cheng" in the title of the state Tongbu wheel should be "multiplied"!

Original formula: 25x32+24 ;

Dismantling the formula to get: 25x4x8+3x8;

Propose a person next to 8 at the same time, and get: 8x(25x4+3);

Simplifying the sub-segment gets: 8x(100+3);

Remove the brackets, and calculate the reputation of the accounting office: 800 + 24 = 824;

25 32 + 24 how to be filial piety and slag manuscript is simple, how to calculate the beam mold.

Split the empty beast clan Ant Fan 32 into 4*8, and use the cheating 25*4 to round up into 100, making the calculation easy.

A simple calculation of 24 25 6 is as follows:
