What is a plus number of 7 and a sum of 3 6, and what is the other plus number?

Because another way to know and find addition is subtraction.

The simple operation is: =

Laws: 1. Multiplicative distributive law.

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.

2. Multiplication associative law.

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.

3. Multiplication commutative law.

The multiplicative commutative property is used to invert the positions of individual numbers: a b = b a4, and the commutative property of addition.

The additive commutative property is used to swap the positions of individual numbers: a+b=b+a5, and the additive associative law.

a+b)+c=a+(b+c)

And - one plus = another plus.

1. Definitions:

In the previous version of the textbook, it was stipulated that when the sum of two numbers A and B was found, the first number A was called the number to be added, and the second number B was called the number added. Addition is one of the mathematical terms, and in the addition equation, the addition of two numbers is called addition. The sum of several identical additions forms a multiplication.

If one addition is 0, the sum is equal to the other addition itself. Adding a number is equal to subtracting the opposite of that number.

2. Addition:

Addition hail fighting is one of the basic four operations, which refers to the calculation of two or more numbers and quantities combined into one number and quantity. The symbol for addition is the plus sign "+", and when adding, the items are connected with a plus sign.

Addition (usually denoted by the plus sign "+") is one of the four basic operations of arithmetic, the rest is subtraction, multiplication, and division. For example, there are a total of three apples and a combination of two apples, for a total of five apples. This observation is equivalent to the mathematical expression "3 + 2 = 5", i.e. "3 plus 2 equals 5".

In addition to calculating fruits, other physical objects can also be calculated. Using systematic generalization, it is also possible to define the source of addition on more abstract quantities, such as integers, rational numbers, real and complex numbers, and other abstract objects such as vectors and matrices.

Addition has several important properties. It is commutative, which means that the order is not important, and it is again interrelated, which means that when more than two numbers are added, the order in which the addition is performed does not matter. Repeat plus 1 is the same as counting; Adding 0 does not change the result.

Addition also follows related operations such as subtraction and multiplication.

Addition is one of the easiest numerical tasks. The most basic addition: 1 + 1, can be calculated by a five-month-old baby, or even by other animal species.

In primary education, students are taught to perform superposition calculations of numbers in the decimal system, starting with a single digit and progressively solving more difficult numerical calculations.

The solution to another number is equal to the sum of two numbers and subtracting a knowing addition number.

Summary. Hello, ** coming to another?

The sum of 7 of the same addition is 63, what is the other addition?

Hello, ** coming to another?

That's the title.

Can you take a picture of me? There's no other one in this.

There are seven additions in total, and this addition is 9, but what about another?

Can't you understand it? According to this grade, there must be a typographical error, and the number of this one addition is about the same.

Good. Well! There is no doubt that the printing is wrong.

That's how it's calculated.

The child wrote correctly, and this addition is 9.

These seven identical additions are nine, so one of them is still 9.

The simple operation of the sum of several identical additions is multiplication, and the sum of seven of the same additions is 63. i.e. 7x 63, x two 63 7

x 9, the sum of the 7 nines is 63

This number is 9, and the other is still 9.

Lane 63 7 is equal to 9, and this addition is 9

7+7=14Answer: And is 14The operation of merging two numbers into one number is called addition. 1.In addition, the number added is called the additive, and the added number is called the sum. Add the number of rotten oranges is the ministry.

It is known that the two additions are 7, and if you have a hand, the addition = 7, and the addition = 7 in the other section, then the buried sum = one addition + another addition.

A: And yes 14
