console.log(mathn.sum([10, 70, 20])); // 100

// Return the next random number in the range (0.0 to 1.0)
console.log(mathn.random()); // 0.8410564055965708

// Calculate your expression if possible
console.log(mathn.calculate('(14 + 1) * 2')) // 30

// Shuffle an array
console.log(mathn.shuffle(['A', 'B', 'a', 'b', '1', '2'])); // [ 'A', 'a', '1', 'B', '2', 'b' ]
console.log(mathn.shuffle(['A', 'B', 'a', 'b', '1', '2']).join('')); // A21Bab

// Also you can spicify a length for it
console.log(math.shuffle([1, 2, 3, 4, 5, 6, 7, 8, 9, 0], 5)) // [ 5, 1, 6, 7, 0 ]

range() Function
