0 54 1 05 0 25 0 2 How to do a simple calculation?

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

Extended Information Vertical Calculation - Calculation Process: First align the last digit of the two multipliers, then use the second multiplier respectively, multiply each digit by a multiplier from the last digit, 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 multiplier first, and finally the product is reduced by the corresponding multiple;

Problem solving: Step 1: 2 54=108

Step 2: 4 54 = 2160

According to the above calculation steps, the combined result is:

If you have any doubts, please ask and be satisfied.

Easy calculation,.

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 problem, we can try to calculate first, and then calculate the multiplication and subtraction operations to get the answer, which is relatively simple.

The detailed and simple calculation process is as follows, so you can get the final answer through the above simple calculation process.

Extended information: Problem solving ideas: Generally, when we do calculations, the subtracted number is larger than the subtraction number.

If the subtraction is smaller than the subtraction, then a minus sign can be proposed to get the subtraction being greater than the subtraction. Then, when you do the subtraction operation, you should start the calculation from the low position. The corresponding number of digits, the subtracted number is less than the subtraction number, then it is necessary to borrow the digit from the higher digit to calculate.

Step 1: 8-0=8

Step 2: 6-0=6

Step 3: 2-2=0

Step 4: 2-0=2

So, the answer that can be obtained through the subtraction operation of vertical calculation is:

This problem cannot be easily calculated, just calculate it from left to right, and the result is.

Measure 9: Back to basics. Generally speaking, it is not advisable to tackle difficult problems before the exam, because there is neither so much time nor necessity.

It is necessary to return to the basics and lay a solid foundation, so that "no points are lost in the basic score" during the exam. No. 10: Time-limited training.

You can find a set of questions (such as 10 multiple-choice questions) and try to complete them within a time limit; You can also find 1 big question and complete it within a time limit. This is mainly to create an exam situation to test one's level of thinking in a stressful state. 11th count:

Activate the mind. You can find some questions and just think about the ideas: what to do in the first step, what to do in the second step......(You don't have to go into details) and then check your own thinking against the answers.

Every exercise should be seen as an opportunity to consolidate knowledge and train skills. The key is to lay a good foundation, be diligent in summarizing, find the rules, and get through everything. Prevention of Test Anxiety Measure 13:

Moderately calm. Students who usually have a flamboyant personality can be a little calmer under the premise of flamboyance; Students who are usually introverted can be a little more open in their calmness. Calm under a certain amount of pressure is a necessary condition for over-performing in the college entrance examination.

Measure 14: Moderate self-confidence. The big exam is approaching, and I often say to the candidates:

All hesitation must be rejected here, and no cowardice will help here. "Self-confidence is the starting point of success; Loss of confidence will inevitably lead to failure. 15th meter:

Moderate motivation. Neither too strong nor too weak motivation is good for the exam; Moderate motivation, maximum efficiency. Expectations are too high, which can easily lead to nervousness, depression, fear and other emotions, which in turn leads to failure in the exam.

The simple calculation process segment is as blind as holding it empty.

Hopefully.

Simplified: ==(==Extended Materials

Easy calculation:

According to the laws of operation and the characteristics of numbers, the decomposition method often flexibly decomposes and recombines the numbers in the equation to achieve rounding and simplification.

Break it down into a "product":

Example 25 32 125

This problem decomposes the factor 32 in the multiplication equation into the form of 4 8, and then multiplies 4 and 25 and 8 and 125 to get the formula of multiplying the whole number of hundreds and whole thousands, which is relatively simple.

Break it down into a "and":

It is to simplify the calculation by splitting a certain number in the operation into a whole thousand or a whole hundred, an integer ten number plus a single digit.

Example 105 36

In this problem, it is easier to split the factor 105 close to the whole hundred into a sum of 100+5, and then use the multiplicative distributive property to calculate.

I'll offer one and see if it's your idea:

x4 4) is 1==(==

The simple calculation of the imitation of the grip process is like a quiet spike:

= (Bikei

Because it is 10, so the person who is the core can change the cautious potato filial piety to simply calculate.
