just a number
When a given set of values for the variables are substituted in the expression the result is the value of the expression.
In a boolean algebraic expression if the ^ is replaced by v and v replaced by ^ then that becomes dual of that boolean expression.
x+5, but the x can be replaced with any variable (i.e. letter)
They are replaced as letters.
A variable is a letter that represents a number. An expression that contains at least one variable is called variable expression, also called algebraic expression. A variable expression has one or more terms. A term is a number, a variable, or a product of numbers and variables. For example,3(x^2)y + 2xy + x - 7 is a variable expression, where you have 4 terms.When working with variable expression, you often use the substitution principle:If a = b, then a may be replaced by b in any expression.The set of numbers that a variable may be represent is called replacement set, or domain, of the variable. To evaluate a variable expression, you replace each variable with one of its values and simplify the numerical expression that results.Example: Evaluate the expression 2x - 4y for x = 5 and y = -9.Solution:2x - 4y= 2(5) - 4(-9)= 10 + 36=46
An equation is called an equation because the root of the word 'equation' is the verb 'to equate'.That is, an equation says that two quantities are equal. This is the vital piece of information that a mathematician learns by inspecting an equation.Combining several pieces of such information like clues to a puzzle let mathematicians and engineers solve systems of equations for the variables involved, though this isn't always possible unless you have at least one equation for each variable.Algebraic methods all derive from what can be done to two equal quantities while keeping them equal, and algebraic substitution derives from the fact that the quantity substituted is equal to the expression replaced.
A very brief and simplified answer is that the Byzantine Empire was conquered by the Seljuk Turks, who themselves were replaced by the Ottoman Turks.
The same as in many other expressions. It is a variable, that is, it can be replaced by any number.
In a perturbed system, writing the equations of motion in a form where the contribution of fast variables is replaced by their average on the corresponding invariant torus.
If the equal sign in a linear equation in two variables is replaced with an inequality symbol, the result is a linear inequality in two variables. 3x-2y>7 x<-5
X is a variable which can be replaced with virtually anything ranging from -infinity to +infinity, imaginary numbers, other variables and even whole other functions.
"Cool" meaning "good" dates from the late nineteen-forties, when "hot" jazz went out of favor, replaced by "progressive" bop or bebop. Mop.
A character code invented by Samuel Morse it is called the Morse code and it was invented in 1844. It was replaced by a simplified International Morse code that is easier to use in 1865.
In a macro, the cell at the intersection of the third column and the fifth row can be referenced as range("C5") or cells(5, 3). In the cells property, the numbers can be replaced with variables.
I am not entirely sure what kind of equation you want to solve. Anyway, if an expression has an exponent of zero, the entire expression is usually equal to 1 (unless you raise zero to the power zero; that's undefined). Perhaps that can help you simplify the expression. For example: if you have an equation such as (x+y+z)0 + 5x + 3 = 10 The entire left expression, (x+y+z)0 can be replaced with 1, thus simplifying the equation.
The expression relates to a concept in Economics know as "creative destruction". This concept describes a process in which industries based on old technology are replaced by industries based on new technology, and with a better result for everyone overall. In this case, the Stone Age ended because stone tools were replaced by bronze tools, and thus began the Bronze Age. When industries seek protection against new competitive technologies, this expression is used to point out that regulation providing protection is not in everyone's best interest.
Simultaneous equation is nothing: it cannot exist.A system of simultaneous equations is a set of 2 or more equations with a number of variables. A solution to the system is a set of values for the variables such that when the variables are replaced by these values, each one of the equations is true.The equations may be linear or of any mathematical form. There may by none, one or more - including infinitely many - solutions to a system of simultaneous equations.
Boolean algebra is an area of algebra in which variables are replaced with 1 or 0 to indicate true or false. This form of algebra became the basis for binary computer programming used in digital electronic development.
The cost to replace grass depends on a few variables. How big is the area that needs to be replaced? Will you be using seed or sod? Will you complete the project yourself or hire a landscape company?
An enum, short for enumerated type, is a variable type that can only take on the values that are declared inside the enum declaration. An enum is declared like a class, except the word "class" is replaced by the word "enum", and the class body is replaced by a list of values that a variable of that type can take on. You can also include methods, instance variables, and constructors in an enum.
The idea is that a regular equation is simply a statement that two quantities are the same; this statement may, or may not, be true - or it may depend on the value of the variables. For example, x + 2 = 5 is true, only if x is replaced with 3. An "identity" is an equation that is true for any value of the variables.
A variable is simply a named value that can be altered by the program. The name is a reference to the memory location where the variable is stored. At compile time, the names are stripped and replaced with memory offsets relative to the program's starting address, referring to memory within the program's data segment, the stack. Dynamic variables cannot be replaced with offsets since they do not exist at compile time. Thus memory is set aside within the program's data segment to store the memory addresses of each dynamic variable and the dynamic variable names are replaced with those data segment offsets. Complex objects are also variables and the memory offsets for an object's members must be stored in an array within the program's data segment. Thus the same array can be re-used for all objects of the same class. Ultimately there are no named variables in machine code, only memory addresses or memory offsets. Constants are treated similarly as machine code does not differentiate a constant from a variable. The term constant is simply an aid to programming, giving the programmer some assurance that a variable will not be altered inadvertently by code outwith his control.
