Hello nets!

You're going to build a simple neural network to get a feeling for how quickly it is to accomplish in Keras.

You will build a network that takes two numbers as input, passes them through a hidden layer of 10 neurons, and finally outputs a single non-constrained number.

A non-constrained output can be obtained by avoiding setting an activation function in the output layer. This is useful for problems like regression, when we want our output to be able to take any value.
