    You may have a typo in the variable or function name or an incorrect import statement.

    However, you can use the mathjs library to perform mathematical operations in your Next.js project.

    1. Install the mathjs library using a package manager such as npm or yarn.

    run npm install mathjs or yarn add mathjs

    1. Import the mathjs library

    import * as math from 'mathjs'

    Try reinstalling mathjs and ensure that you’re importing it properly.

    import { math } from 'mathjs';

    Also make sure there are no typos. Its "math.evaluate" and not "maths.evaluate"

    const result = math.evaluate('2 + 3');

    For different usecase:
    If you want to render math expressions instead, try using "Ketex".

    Here is an example on how to use it:

    import { useEffect } from 'react';
import 'katex/dist/katex.min.css';
import katex from 'katex';

const options = {
  throwOnError: false,
  errorColor: '#cc0000',
};

function MathComponent() {
  useEffect(() => {
    katex.render('c = \sqrt{a^2 + b^2}', document.getElementById('math'), options);
  }, []);

  return (
    <div id="math"></div>
  );
}

export default MathComponent;
