It is not a mathematical symbol. For example in X - 3 9 X is the Variable. Means multiply x with terms x-1 x-2 x-32 1 and stop with 1.

And if x0Then x -x ie. Y 2x 7 has a degree of 1 so it is a linear equation. IF x 0 then x x.

The symbol is also commonly used to show a minus or negative number such as 2. Recognizing a pattern such as the difference of. 4 is less than 5.

Linear equations are easy to solve. Dont multiply by 0. When x 1 or larger x.

Divide every term by the same nonzero value. Expanding the opposite of factoring may also help. We say that the function covers X relates every element of it.

Greater than or equal to. Cubic equations are harder again but there are. Eg using Quoras math markup if I write 23 and put it in math mode it comes out as 2 3 which is the way exponentiation is typically shown in mathematics.

X x 2 x. For example the set of all x such that x is less than 5 can be written as xx5. 5w2 3 has a degree of 2 so it is quadratic.

The letter X is often used in math to mean a value that is not yet known. It was a negative number and modulus turned it into a positive value. Or or.

5 4 x y means x is greater than or equal to y. Higher order equations are usually harder to solve. It is called a Variable.

Hope your doubt is clear. See our page on Subtraction for more. Is used when one or more numbers are to be subtracted for example 2 2.

But some elements of Y might not be related to at all which is fine 2. Clear out any fractions by Multiplying every term by the bottom parts. The value of x must be an integer 0 or larger.

In mathematics brackets of various typographical forms such as parentheses square brackets braces and angle brackets are frequently used in mathematical notation. The factorial of a number is represented by the exclamation point. X means modulus of x.

Which in this case equals 12.
