What are these two numbers? What is the sum of two numbers

Let the two numbers be x,y

a=x+yb=x*y

p says I don't know, and you don't know how to say that a cannot be equal to the sum of two prime numbers, or the sum of a prime number greater than 25 and the sum of another number.

Then the possible values of a are 11, 17, 23, 27, 29b.

Q knows the value of b, but he doesn't know the answer: There are no less than two numbers in it that are equal to b.

So the value of b must be: one of 42, 72, 120, 180.

So a is 2+21=23, 3+14=17.........12+15=29p got the answer.

Then 2+21, 3+14, 6+7, 2+36 ,......There is only one number equal to a in 12+15, 3+14=8+9=17, 2+21=18+15=23, 3+24=12+15=27

So a can't be one of 17, 23, 27.

So A must be one of 13, 38, 22, 18, 41, 36, 29.

As we know earlier, a must be a number in 11, 17, 23, 27, 29.

So a=29

Q said that he also knew the answer.

2*27,3*26,4*25,…14*15 is the same number as 42, 72, 120, 180 is 180

So x=9 y=20

Wow. Upstairs, your reasoning is so complicated!

The sum of two numbers is the addition of two numbers. For example, the sum of 5 and 7 is 5+7=12.

Additive operations1. Add two numbers with the same sign, take the same symbol as the additive, and add the absolute value.

2. If the absolute value is equal, the sum of the two numbers of the opposite number is 0; If the absolute values are not equal, take the sign of the addition with the greater absolute value, and subtract the smaller absolute value from the larger absolute value.

3. Add two numbers that are opposite to each other to get 0.

4. Add a number to 0 and still get this number.

5. Two numbers that are opposite to each other can be added first.

6. Numbers with the same symbol can be added first.

Explanation 1: Think of "2" as a unit, how many units there are in the total, or how many "2s" there are in the total.

That is, take out 2 for each count, (count one, take out 2; count two, and take out two more; Count three, and take out 2 more;

It's called "2 2 Places", and the 2 elements become a combination.

Explanation 2: The meaning of 2 numbers of 2 places is: 2, 4, 6, 8, 10 .......

Suppose there are 6 1s here, and our 2 2 numbers are the first 2 1s are counted as a group, the middle 2 1s are counted as a group, and the last 2 1s are counted as a group. The count is 2, 4, and it only takes 3 times to count 6 1s for 2 numbers, and 6 times for 1 counts.

書数 (shǔshù), which has both verb and noun parts of speech, refers to the calculation of detailed numbers in a certain way or way, usually with a wrench finger or mouth or silent recitation in the heart, which is a more common and common mathematical behavior.

Do you want to ask, "What do you mean by the number of two rolls and two places"? It means the following two ways:

1. Treat "2" as a unit, and the total number of units is several units or the total number of "2s". It is to take out 2 for each count, 2 for the number one, 2 for the number two, and 2 for the number three. It is called two two earth numbers, that is, two elements become a combination.

2. Its meaning may also be counting, that is, such a number. Suppose there are 6 1s here, and the two two numbers are the first two 1s are counted as a group, and the last two 1s are counted as a group, and the count is . It only takes 3 times for two grandsons to count 6 1s, and it takes 6 times to count them one by one.

Two numbers = x, y

The sum of the two numbers is 792

x+y=792 (1)

The last digit of one of the numbers is zero, and if you remove the zero of the smart fiber file, it will be the same as the other number.

x=10y (2)

from (1)

x+y=792

10y+y=792

y=72x=10y =720

The two numbers are vertical bands: 720, 72

The number is divided by Na or 52 and 4, and divided by 40 is also 4, which means that this number is 4 more than the common multiple of 52 and 40.

The least common multiple of 52 and 40 is.

This number is 524+520n (n is a natural number).

The minimum number is 524, (it is okay to say that the minimum is 4). Can't find the biggest one.

Inexplicable questions, and inexplicable answers!

Two numbers (divided) are also called the ratio of two numbers. The ratio (the former term) is equivalent to the numerator in the fraction, and the latter term is equivalent to the (denominator) in the fraction.

For example: 2:3 is equivalent to 2 3 is equivalent to 2 3, and that's what it means.

The division of two numbers is also called the ratio of two numbers, the first term of the ratio is equivalent to the numerator in the fraction, and the latter term is equivalent to the denominator in the fraction.

For example, 1 to 3 is equivalent to 1 3 is equivalent to 1 3.

The division of two numbers is also called the ratio of two numbers.

The sum of two numbers is called the sum of two numbers.

For example, 2+3=5 5 is the sum of these two numbers.

There are similarities.

Subtract two numbers to get the difference; Multiply two numbers to get the product; Divide two numbers to get the quotient.

Because the addition + addition = sum, so the sum of any two numbers is added, for example, Xiaomi's Chinese participation is 95 points, and his math score is 80 points, so how many points does his Chinese math have in total? That is, 95 + 80 = 175 points is the sum of two numbers, generally, the total number of two data added up is called the sum of two numbers, and 175 is the sum of 80 and 95, if there are n numbers then the total number he adds up is the sum of n numbers, such as 1 + 2 + 3 + ...100=5050, then 5050 is the sum of 100 numbers from 1 to 100.

It is called sum, and the result of adding two numbers is called sum.

The operation of the sum of two numbers is called "addition operation", which is the addition of two numbers.

The sum of two numbers is the addition of two numbers, and the difference between two numbers is the subtraction of two numbers.

Hello, the sum of two numbers is called the sum of two numbers, and you can also call it the number, the result, the answer, and so on.

The result of the addition of two numbers is called the sum of the two numbers.

The sum of two or more numbers. For example, the sum of five and seven is twelve.

The sum of two numbers is called the sum of two numbers.

An sum is the addition of two numbers.

The difference is the subtraction of two numbers.

Add two numbers to get the sum, multiply the two numbers to get the product, and divide the two numbers to get the quotient.

The sum of two numbers is the sum of two numbers.

It's called "and". Addition + Addition = And.

The result of adding two numbers is called sum.

And "Ah!

Multiply by the "product".

Except is "quotient" minus "poor".

You said it was peace, but you don't know what it's called?

That's called summing.

Why is there such a topic?

Summary. Hello, because + 21, so =21 3=7, and because 63, so 7 =63, =63 7=9 so the answer is: 7,9

And each represents a number, think about it, what number do they all represent-=2-Hello, because + 21, so =21 3=7, and because 63, so Qin Bo Hood is disgusted 7 =63, =63 7=9 So the answer is silver chop: 7,9

Okay, wait a minute.
