Difference between variable and constants in visual basic?
"Memory locations that hold data that can be changed during project execution are called variables; locations that hold data that cannot change during execution are called constants"
What is the GCF of the first two terms of the last two terms for the polynomial 2m3 plus 6m2 plus 3m plus 9?
The GCF of the coefficients and constants i 1. The GCF of the variables is also 1.
What has several functions?
Module can, among other things, such as variables or constants, include one or more functions.(A term function can not be used in a contex of object oriented programming. Substitute for this is called a method. Method is included in class.)
What are universal economic constants?

What is the difference between echo and print and printf in PHP?
The print function is slightly more dynamic than the echo function by returning a value, and the echo function is slightly (very slightly) faster. The printf function inserts dynamic variables/whatever into wherever you want with special delimiters, such as %s, or %d. For example, printf('There is a difference between %s and %s', 'good', 'evil') would return 'There is a difference between good and evil'.

What is the difference between a term and a polynomial?
A term only has variables and constants multiplied among themselves (or, in some cases, divided), such as 5xy, or -3x3. A polynomial is the sum of several such terms.
Compare and contrast variables and constants?
In Computer Programming and Mathematics, variables and constants are ways to refering to a value. For example X=1 and Y=2 The difference being, variables are meant to be arbitary and changable, while constants are meant to be fixed and unchangable. For example, there is no reason for the value of Pi to change. So the value of Pi would best be represented by a constant.
What are constants and how they are different from variables?
Constants are fixed numbers that never change, they always stay the same. Variables are number that can change, they 'Vary'.
What variables that do not change?
The ones called constants.
