Tips for Students on How to Do Math in JavaScript with Operators

Mathematics lies at the heart of just about everything in programming. Understanding how to implement mathematical principles into JavaScript is necessary for building a functioning platform that performs its intended usage. Many of even the most basic tasks that JavaScript is used for involve creating a mathematical output - such as calculating graphics ratios, arriving at price estimations, and tallying inventory. 


Doing math in JavaScript is central to using the programming language to its full capacity. It is not necessary to have an incredibly high level of mathematical understanding in order to squeeze the most out of JavaScript’s mathematical possibilities. Simply taking some basic math courses can help to achieve the level needed for most programming. Learning JavaScript generally entails taking a course, either with online tutors who provide lessons and homework or by consulting programming experts who have written guides on the subject.

When it comes to learning JavaScript through online courses, many math students may find themselves struggling with the level of hw they are being assigned. Luckily there are expert writers online who can help and can do all math homework for me when the workload becomes overwhelming. Even mastering the basics of mathematics is usually enough to suffice for doing math in JavaScript.

To properly implement this mathematical understanding into a useful function in JavaScript, it’s crucial to have an understanding of exactly how the mathematical properties of JavaScript function. JavaScript relies on numbers and operators in order to create mathematical expressions and calculations. Students may be left asking themselves exactly what they mean, but here we’ve put together a quick guide for how to do math in JavaScript.


When implemented in JavaScript, numbers define the values and ranges with which any given mathematical expression is going to work. While the function of an expression may remain constant, the input and output numbers are subject to change based on the values they are intended to represent in the overall equation.

Variables and operators

As is the case with any expression of calculus mathematics, there is the need to define the variable which will produce the output of a function. Within a given operation, the numbers and operators come to define the final calculation of a given variable. For example, in the simple operation, (10+x=y), both (x) and (y) serve as variables. (+) serves as the operator that defines the output value of (y) as a variable and vice versa when solved for (x). In order to make proper use of these mathematical elements, it’s necessary to understand the main math operators JavaScript uses.

Common JavaScript operators:

  • Addition and subtraction
  • Multiplication and division
  • Modulo (or the calculation of a remainder following an equation)
  • Exponentiation (raising one number to the power of another)
  • Increment and decrement
  • Assignment operators  

For most aspiring programmers, these JavaScript mathematical operators should cover just about everything you need for writing most code. Knowing how to add, subtract, and how to multiply in this programming language is often all that most entry-level programmers will find themselves needing to know. However, in order to use the aforementioned programming operators, students need to familiarise themselves with how these operators appear in the code itself.

How to write common JavaScript operators

  • Addition is performed using the (+) symbol
  • Subtraction of one number from another is performed using the (-) symbol
  • Multiplication of two numbers is performed using the (*) symbol
  • Division of one number into another is performed using the (/) symbol
  • The modulo of an equation is calculated using the (%) symbol
  • Exponentiation of one number by the power of another is performed using the (**) symbol
  • Assignment is performed with the use of the (=) symbol

By implementing these operators into even the most basic mathematical expressions on JavaScript, it becomes possible to begin to perform mathematical operations through the code. By stringing together these mathematical expressions, programmers can create increasingly more complex operations that their code can solve.  

Getting to grips with these basic mathematical facets of JavaScript helps greatly when it comes to solving using the JS programming language. As students advance in their knowledge of JavaScript, they can get creative and use the language to solve many different kinds of complex and dependent calculations. Getting to grips with the most basic of JavaScript operators is the first step on the exciting ladder of performing maths through code.
