Octave Arithmetic Operators
In this tutorial, we will learn about Octave Arithmetic Operators. Arithmetic operators can perform various mathematical operations on variables, including operations on scalars and vectors.
Octave Arithmetic Operators
An arithmetic operator is a symbol that Octave uses for arithmetic operations like addition, subtraction, multiplication, division, and exponentiation.
The arithmetic operator’s symbols are as follows:
Arithmetic Operation 
Operator Symbol  Example 
Addition

+  a + b 
Subtraction  –  a – b 
Multiplication  *  a * b 
Left Division
Right Division 
\
/ 
a / b 
Power/Exponentiation  ** or ^  a ** b or a ^b 
Example
Let’s compute the sum of 10 and 25.
In this example, we will declare two scalar variables. Add the variables with the addition operator and print the result.
a = 10;
b = 25;
result = a + b ;
