Why is mobile phone calculator 10%+20% equal to 0. 12?

1, because the mobile phone calculation 10% is correct, but when 20% is added, the mobile phone will default to 0. 1. 1 * 0.2. This adds up to 0. 12. When calculating 10%+20%, the mobile phone calculator calculates a+a*b=0. 12.

2. If you use the percent sign as the separator when you enter 20%, the calculation result is correct. In this case, the mobile phone calculator interprets 10% plus 20% as 10% plus 0.2, and then calculates the result of 0. 12.

3.% plus 20% is not equal to 0. 12. Because 10% is110, 20% is 2/ 10, and it is 3/ 10, not 0. 12. 10% plus 10% equals 20%, which means that in a system. The concentration cannot be added directly because it is not in a system and cannot be added directly.

When you add two percentages together, they represent the percentage relative to the total. So if you want to calculate 20%+ 10%, you are actually calculating 0.2+0. 1. So 20%+ 10% is equal to 0.2+0. 1, which is 0.3.

5. The mobile computer 10%+ 10% equals 0. 12 for the following reasons. There is a Bug in the mobile phone, but the final result is caused by the logic of the calculator to handle the operation symbols. When 10%+ 10% is calculated on smart phones such as OPPO, Huawei, Apple and Xiaomi, the result is 0. 1 1 or 0 12 instead of 0.2.

Why is 20%+20% equal to 0.24?

Why is 20%+20% equal to 0.24?

%+20% is not equal to 0.24 because 20%+20%=0.2+0.2=0.4.

Twenty percent is 0.2. The analysis process is as follows: 20% is converted into decimal du, which is to divide the molecule by the wisdom mother. The mathematical expression dao is: 20÷ 100=0.2, so 20% is 0.

Generally speaking, there may be something wrong with the software. Please try again.

The general algorithm is 20×( 1-20%)= 16 yuan, and the one-step calculation method is 20-20= 16 yuan. From the above two examples, we can see that the one-step calculation method involving percentages has the following conversion relationship with the calculation method we use every day: A b% of the one-step calculation method is equal to A (1 b%) of the general algorithm.

Why is10%+10% = 0.11on some mobile phone calculators instead of 0.2?

Why is10%+10% = 0.11on some mobile phone calculators instead of 0.2?

1. From the above analysis, it can be seen that10%+10% = 0.11is not a bug of the mobile phone calculator, nor is it a mobile phone poisoning. It's just different from the calculation method we usually use.

2. Because 10% is not only a number, but also an operator, and first an operator, then a number. Percentages are different from fractions. A fraction can represent both the number of copies and a number, while a percentage can only represent the number of copies, so a fraction can have units and a percentage can't.

3. Hello, the mathematical calculation of this question is 0. 1+0. 1=0.2, so I disagree with10%+10% = 0.1.

4. Because the following 10% system thinks it is 10%× 10%, it is 1%,10+1%,and the result is1/.

5. Hello, your daughter should use a calculator to get this result, because the calculator interprets "+10%" as a percentage, and the result of adding "0. 1" to "0. 1" is 0.1.

Why is it 20% on the calculator?

Why is it 20% on the calculator?

At first glance, it seems to be a Bug, but the final result is caused by the logic of the calculator to handle the operation symbols. When calculating "10%+ 10%" with the self-contained calculators on smart phones such as OPPO, Huawei, Apple and Xiaomi, the result is 0. 1 1, not 0.2.

If the operand to the left of% is positive, the structure of modulo division is positive or 0.

Because the mobile phone calculation 10% is correct, but when 20% is added, the mobile phone will default to 0. 1. 1 * 0.2. This adds up to 0. 12.

How to use the percentage on the calculator How to calculate the percentage with the calculator?

1. Step 1: Open the calculator and press "c" to clear the screen. Step 2: Enter the required percentage. Step 3: Click the multiplication symbol on the calculator. Step 4: Enter the proportion (the number here is 5 as an example, and the proportion is 20). Step 5: Click the "%"sign on the calculator after completion to get the percentage of this number.

2. How to calculate the percentage of A to B with a calculator: According to this formula, for example, if you calculate 4404÷63925× 100 with a calculator, the result will be: 89 is 89%(% is added manually, the calculator will not display it, and you don't need to press the "%"key when calculating).

3. How to use the percent sign in the calculator: enter the number first, and then enter the percent sign, which is equivalent to dividing the previous number by 100. Percent sign: a sign (%) indicating that the denominator of a fraction is 100. For example, 32% is 32%, which is equivalent to 0.32 of a decimal.
