## Algorithm

### Test

```/**
* Multiple (x × y):
*
* @param x1 Number X
* @param x2 Number Y
* @return {Array}
*/
function neuron3(x1, x2)
{
math.config({number: 'BigNumber', precision: 64}); return [math.eval(Number(x1) + '*'+Number(x2)).toString()];
}

/**
* x to the 2 (x²): x squared
*
* @param x1 Number X
* @return {Array}
*/
function neuron7(x1)
{
var outputs = [];
outputs[0] = x1;

arr = neuron3(outputs[0], outputs[0]);
outputs[1] = arr[0];

return[outputs[1]];
}

/**
* 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()];
}

/**

* @return {Array}
*/
function neuron744(x1)
{
var outputs = [];
outputs[0] = x1;

arr = neuron7(outputs[0]);
outputs[1] = arr[0];

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

return[outputs[2]];
}
