How do I use a calculator to do a continuous addition operation?

Operational Tool: Calculator.

1. First of all, take an accumulation formula as an example to illustrate this function of the calculator. As shown in the figure below.

2. Calculate the multiplication of 120*12 on the calculator first, and remember not to press the sign.

3. Then press the M+ key on the keyboard, which is the accumulation key.

4. After pressing the accumulation button, you can see the multiplication of 120*12.

5. At this time, press the equation 240*2 input, and also do not press the number.

6. Press the M+ Accumulation key once, and then the number of the formula will be displayed.

7. If there is no other formula, you need to press the MR button at this time.

8. You can get the cumulative number. The number 1920 is followed by the word m showing the cumulative calculation.

Calculate 2*3 first to get the product, press m+, then +3 and then press m+, then *4, press m+, and finally calculate 5*6, don't press equals! Just press the mec and you're fine.

Here's how to use a calculator for mixed calculations:

1. There is a simple calculator, the display screen is relatively large, and the keys are relatively large, relatively simple, and you can use the multiplication and division mixed operation very quickly.

2. You can perform a one-time operation on the following question: "(101*273)-(458 34)=".

3. Generally speaking, it is necessary to calculate "(101*273)=" to get the result first, and record it on paper for later use.

4. Then calculate the answer to "(458 34)=", write it on paper, and subtract the results before and after, which is relatively slow and has a high probability of error.

5. It is relatively simple to use the calculator to calculate at one time, and make full use of it"m+"with"m-"The role of this button is to perform a hybrid operation.

6. The order of the keys is: after the first "101*273", press and hold again"m+"button, then press "458 34" and"m-"and finally press "MRS.""The results are out, and there is no need to record them on paper.

7. The steps of using the calculator are very simple, that is, to compare the proficiency of the operation, especially to understand"m+"with"m-"\”mrs", it is necessary to memorize and calculate the previous calculation results.

How to multiply the calculator and add it together.

Hello, counting and laughing at the multiplication of the calculator, how to operate the addition 1, take an accumulation formula as an example to illustrate the function of the calculator. 2. Calculate the multiplication of 120*12 on the calculator first, remember not to press the number, to press the m+ key on the keyboard, this is the accumulation key. 3. After pressing the accumulation key, you can touch the mu calendar to see the multiplication of 120*12.

4. At this time, press the equation 240*2 input, also do not press the number, to press the M+ accumulation key once, then the number of the formula will be displayed. 5. In the absence of other calculations, you need to press the MR key at this time to get the accumulated number. If you need to perform the next calculation, you need to press the MC key to clear the M gauge sign.

This reverts to normal calculations. 6. For such an additive use, the formula that needs to be accumulated can be addition, subtraction, multiplication or division, if we need to equal the sum, difference, product and quotient of each equation, we can use this function.

Summary. Kiss, calculator multiplication, plus operation method tutorial is as follows:

1.Let's use an accumulation formula as an example to illustrate the function of the calculator.

2.Let's calculate the multiplication of 120*12 on the calculator first, remember that you can't press the = sign, you have to press the m+ key on the keyboard, this is the accumulation key.

3.Then press the accumulation button and you can see the multiplication of 120*12.

4.At this time, press the equation 240*2 input, and also do not press the = sign, but press the m+accumulation key once, and then the number of the equation will be displayed<>

Kiss, calculator multiplication, plus operation method tutorial is as follows:1Let's use an accumulation formula as an example to illustrate the function of the calculator.

2.Let's first calculate the multiplication of 120*12 on the macro calculator, remember that you can't press the = sign, you have to press the m+ key on the keyboard, this is the accumulation key. 3.

Then press the accumulation button and you can see the multiplication of 120*12. 4.When this or elimination, press the equation 240 * 2 input, the same do not press the = sign, to press the m+ accumulation key shirt once, then the number of the equation will be displayed<>

Dear, the teacher will give you an example, suppose we calculate the content as: 11 11 + 22 22 specific as digging fingers: 1

We can judge the family to perform ordinary calculations first, and get the answer: 11 11 + 22 22 = 6052Calculation of additional functions:

Type 11 11 and press = to get the answer 121! Tease Lee.

Dear, what I want to say about Mr. Lian is:1Then press the M+ key to add the number. 2.Press the MR key to re-call the rotten spike 3The answer can be found after the hunger is divined!

First calculate the multiplication of 120*12 on the calculator, remember not to pronounce the scum press the = sign, to press the m+ key on the keyboard, this is the accumulation key. 3.After pressing the accumulation button, you can see the multiplication of 120*12.

4.At this time, press the equation 240*2 input, also do not press the = sign, to press the m+ accumulation key once, then the number of the envy Gao Bi formula will be displayed.

How to implement the calculator's add-and-subtract function:

For example, to calculate (A B) + (C D) + (E F), first calculate A B and then press M+, then press C D, then press M+, then press E F and then press M+, and then press Mrc is the result. In the same way, if you subtract continuously, press m-.
