Variables are used to store information to be referenced and manipulated in a computer program. They also provide a way of labeling data with a descriptive name, so our programs can be understood more clearly by the reader and ourselves.

Hence, the degree of the monomial 7y is 1.

A term is a single mathematical expression. It may be a single number (positive or negative), a single variable ( a letter ), several variables multiplied but never added or subtracted. Some terms contain variables with a number in front of them. The number in front of a term is called a coefficient.

In computer programming, a variable or scalar is a storage location (identified by a memory address) paired with an associated symbolic name, which contains some known or unknown quantity of information referred to as a value or In easy terms a variable is container for different types of data (like integer, float.

Variables are data values that can change when the user is asked a question, for example, their age. Variables may change during program execution. A variable is a memory location . It has a name that is associated with that location.

Most programming languages have a data type called a string, which is used for data values that are made up of ordered sequences of characters, such as “hello world”. A string can contain any sequence of characters, visible or invisible, and characters may be repeated.

Functions are “self contained” modules of code that accomplish a specific task. Functions usually “take in” data, process it, and “return” a result. Once a function is written, it can be used over and over and over again. Functions can be “called” from the inside of other functions.

The function contains instructions used to create the output from its input. It’s like a cow that eats grass (the input) which its body turns into milk which a dairy farmer then milks (the output). For example, programming functions might take as input any integer or number.

To create a function, you write its return type (often void ), then its name, then its parameters inside () parentheses, and finally, inside { } curly brackets, write the code that should run when you call that function.

A function rule describes how to convert an input value (x) into an output value (y) for a given function. An example of a function rule is f(x) = x^2 + 3.
