## Algorithm

### Test

```/**
* Plus (x + y): The addition of two whole numbers is the total amount of those quantities combined.
*
* @param x1 first number
* @param x2 second number
* @return {Array}
*/
function neuron1(x1, x2)
{
math.config({number: 'BigNumber', precision: 64}); return [math.eval(Number(x1) + '+'+Number(x2)).toString()];
}

/**
* Minus (x - y):
*
* @param x1 Number X
* @param x2 Number Y
* @return {Array}
*/
function neuron2(x1, x2)
{
math.config({number: 'BigNumber', precision: 64}); return [math.eval(Number(x1) + '-'+Number(x2)).toString()];
}

/**
* a + b; a - b:
*
* @param x1 a
* @param x2 b
* @return {Array}
*/
function neuron717(x1, x2)
{
var outputs = [];
outputs[0] = x1;
outputs[1] = x2;

arr = neuron1(outputs[1], outputs[0]);
outputs[2] = arr[0];

arr = neuron2(outputs[0], outputs[1]);
outputs[3] = arr[0];

return[outputs[2], outputs[3]];
}
