For example: A, B, C and D are not zero. :D

What do the terms in mathematics mean? It is easy to address, remember, explain and use, and the names given to a part of the formula are universal in mathematics.
-A is a project,
1+x+xy+xyz is four terms.
respectively are
1，x，xy，xyz
3x-8y+2z-6 is four terms.
respectively are
3x，-8Y，2z，-6
What does factorization mean in mathematics? Factorize the escape value.
Factorization expression
Decomposition means decomposition. ...
What does ""mean in mathematical calculation? In mathematics, it is a parallel symbol.
In physics, it is the symbol of parallel resistance calculation.
Parallel resistance calculation
AB=A*B Dan (A+B)
What do (,] and [,) mean in mathematics? The first one is the number on the left, not the number on the right. The second one is just the opposite.
What is the meaning of * in mathematics? Let me answer you ~ ~
This is just a hypothetical operation or shorthand.
For example, two real numbers A and B need operation (a+b)? -b to get the result, the operation process is to find the sum of a and b, then square the sum, and finally subtract B.
We can artificially specify an operator "*" to represent the process, and record it as a * b.
Have a*b=(a+b)? -B.
Think of "a*b" as (a+b)? -b The abbreviation of this operation process will do.
The specific operation process is as stipulated in the title, and I am just giving an example.
If the topic is a*b=ab+b, then 3*2=3? 2+2=8
You can think of a*b as the abbreviation of AB+B.
"*" is just a symbol we wrote casually, indicating the operation process. It can also be expressed by other strange symbols.
This is similar to a function expression, just like y=f(x), except that f(x) is called the mapping of x in the function.
What does at least mean in mathematics? It means the least. For example, at least two angles in a triangle are acute,
That is, at least two angles are acute angles, and there can be more than one, that is, there can be no acute angle or no acute angle, but there can be at least two acute angles and three acute angles.
What does it mean in mathematics? Let me answer you ~ ~ This is just a hypothetical operation or abbreviation. For example, two real numbers A and B(A+B) need to be operated. -b To get the result, the operation process is to first find the sum of A and B, then square the sum, and finally subtract B. We can artificially specify an operator number "*" to represent this process, which is marked as a*b and a*b=(a+b)? -b actually thinks "a*b" is (a+b)? The abbreviation of -b is enough. The specific operation process is explained in the title. I am just giving an example. If the topic is specified as a*b=ab+b, then 3*2=3? 2+2=8 You can think of a*b as the abbreviation of AB+B, and "*" is just a symbol we write casually, indicating the operation process.

What is the meaning of "L" in mathematics? This kind of question is completely meaningless. There are too many places with L in mathematics to answer without context.
The sources of L are mostly symbols related to letters or mathematicians starting with L, such as length, lower triangular matrix, linear operator), Laplace transform, Lebesgue integral, etc.
What does height mean in mathematics? If a vertical line is drawn from the vertex of a triangle to its opposite side (or the straight line where the opposite side is located), then the line segment between the vertex and the vertical foot is called the height line of the triangle, which is called height for short.
Obviously, the height of a triangle is a line segment. Because a triangle has three sides, it has three heights.
Draw a vertical line from any point on one side of the parallelogram to the opposite side (or the line where the opposite side is located), and the line segment between this point and the vertical foot is called the height of the parallelogram.
The side where the vertical foot is located is called the base of the parallelogram.
According to the definition, a parallelogram can have countless heights, but only four bases!
The line segment from trapezoid to vertical foot is called the height of trapezoid! The side where the vertical feet are located is called the bottom of the trapezoid.
According to the definition, a trapezoid can have countless heights, but only two bottoms!
Lead a vertical line to the bottom surface, and the line segment between this point and the vertical foot is called the platform height.
It is easy to know from the definition that a platform can have countless heights, but there are only two at the bottom!
