+## Introduction to the Design a Sum All Numbers Algorithm
+
+In this lab, you will design a sum all numbers algorithm. This algorithm takes an array of two numbers and returns the sum of those two numbers plus the sum of all the numbers between them.

+# --description--
+
+In this lab, you will need to design a sum all numbers algorithm.
+
+Fulfill the user stories below and get all the tests to pass to complete the lab.
+
+**User Stories:**
+
+1. You should have a function named `sumAll` that accepts an array of two numbers.
+1. `sumAll([n, m])` should return the sum of `n` and `m` plus the sum of all the numbers between them. The lowest number will not always come first. For example, `sumAll([4,1])` should return `10` because sum of all the numbers between `1` and `4` (both inclusive) is `10`.
+
+# --hints--
+
+You should have a function named `sumAll`.
+
+```js
+assert.isFunction(sumAll);
+```
+
+`sumAll([1, 4])` should return a number.
+
+```js
+assert.isNumber(sumAll([1, 4]));
+```
+
+`sumAll([1, 4])` should return `10`.
+
+```js
+assert.equal(sumAll([1, 4]), 10);
+```
+
+`sumAll([4, 1])` should return `10`.
+
+```js
+assert.equal(sumAll([4, 1]), 10);
+```
+
+`sumAll([5, 10])` should return `45`.
+
+```js
+assert.equal(sumAll([5, 10]), 45);
+```
+
+`sumAll([10, 5])` should return `45`.
+
+```js
+assert.equal(sumAll([10, 5]), 45);
+```
+
+# --seed--
+
+## --seed-contents--
+
+```js
+```
+
+# --solutions--
+
+```js
+function sumAll(arr) {
+  let sum = 0;
+  
+  arr.sort((a, b) => a - b);
+
+  for (var i = arr[0]; i <= arr[1]; i++) {
+    sum += i;
+  }
+
+  return sum;
+}
+```
