A variable is an unknown, so algebra equations contain them. there are lots of different ways you can see a variable though whether it be in chemistry physics , business or just a math course. They can be huge equations or just simple ones. But there will be an unknown. Usually denoted as a "x" or "y" etc
For example 4x+3y^2+10x-2y+8x
It is a constant.
4x- x
An expression.
an algebraic expression
Like terms.
The control does not contain a variable!:)
math statements that contain variables are expressions or equations that have a letter or symbol that represents a number or value. for example, if (2+N=7), N is the variable and N=5 hope this helps
A local variable is a variable that can only be called on by the module. Where as a global variable can be called upon by any module. Only statements made inside the same module can call on a local variable.
Decision statements are statements that are used for taking logical decisions. They contain a condition whose output is a boolean true or false. Ex: if (name.equals("Rock")) { System.out.println("Hi Rocky!!!"); } The output of the if condition will depend on the value that the variable name holds. This is a decision statement
Usually, the name of the variable can be most anything. This type of variable is called a LOGICAL variable.
the variable that is most difficult to test
The if and switch statements are commonly referred to as decision statements. When we use decision statements in our program, we're asking the program to evaluate a given expression to determine which course of action to take. It decides the control flow of the program.
A variable is an entity that may change its value. In a program, the result of the processing statements are stored in the computer's memory.
It is a constant.
All of them contain variable amount of minerals.
boolean
The program's statements, just like any other variable.
