You cannot plug in a variable, what you do is plug in the value for a variable. If you know the value of the variable in an equation (or formula), the process of replacing that variable whenever it appears in the equation by its value is called plugging in the value for the variable.
yes
In mathematics, a variable is a representation, in the form of a letter, of a numerical value. Variables are traditionally used when the value it represents is either unknown or can vary.
that means to replace the variable with it's value, and then do all the mathematical symbols as normal (+-x/)
In a linear relationship such as represented in the equation x= b+ay. The relationship between the x and y is a direct variation. This basically means that in the above equation/situation the value of the y variable is proportional to the value of the x variable. In other words the x and y increase or decrease proportionately. If the x value decreases the y value decreases. If the x value increases so does the y value. Now in a quadratic relationship it is a little different in that this kind of function is actually in the shape of a parabola. The equation for this relationship is ax2 + bx + c = y. The parabolic relationship exists when one variable depends on the square of another and this relationship is often expressed in saying that the y variable varies directly with the square of the x variable.

A function that is used before an variable to increase or decrease its value
To calculate an increase, you can use the formula: increase = (new value - original value). To calculate a decrease, you can use the formula: decrease = (original value - new value). The percentage increase or decrease can be found by dividing the increase or decrease by the original value and multiplying by 100.
I think you mean, decrease "IN" value which means something is not as valuable any more.
yes
A function that is used before an variable to increase or decrease its value
In mathematics, a triangle in front of a variable typically denotes the concept of "change" or "difference." This notation is often used in calculus to represent a derivative, which measures the rate at which a function changes with respect to its input variable. The triangle, also known as the "delta symbol," is used to indicate a small change in the variable, allowing for precise calculations in calculus and other areas of mathematics.
The order of the operations: --p means: decrement the variable, then fetch the new value p-- means: fetch the old value, then decrement the variable
Calling a function by value means the variable will be copied. That means that, any changes you make to the variable will be applied to the copy, and not the real one. If you pass by reference, the actual intended variable is modified.
variable definition means to declare the variable with its value. for example:- int i=10; this statement is a combination of declaration of integer i and assign its value to it,so it is a definition statement Note: assigning a value is not essential.
It Means addeding all the numbers to get the answwer.
A dependent variable is one in whose experimental or analytical value is determined by the value of the independent variable. An independent variable is not determined by any other variable, but rather is an input value. For example in the equation y = 3x y is dependent and determined by the value of the independent variable x
