ExpressMath is a parser for its own math/computational problem markup language.
The markup language is inspired from Jinja template. See example for better understanding of how this works

Installing

ExpressMath installation using Composer

composer require terrydjony/express-math

require 'vendor/autoload.php';

$mathlang = 'Jika Andi punya {{ a }} bola, dan Budi punya {{ b }} bola, maka jumlah bola mereka adalah {% a + b %}';
$config = [
    'a' => mt_rand(2,5)
];

$expressMath = new ExpressMath();

$eval = $expressMath->eval($mathlang, $config);

var_dump($eval->getProblem()); // Jika Andi punya 4 bola, dan Budi punya 56 bola, maka jumlah bola mereka adalah
var_dump($eval->getVariables()); //   ['a' => 4, 'b' => 56]
var_dump($eval->getValue()); // 60
