It was difficult wiring them together as both sensors require the GND and 5V pins on the Arduino. However, thanks to my friend, I learned that I can use the breadboard to help wire them in a series.
Basically, it's where you use one end of the jumper wire to connect to the GND pin on the Arduino Uno for example. Then you'd connect the other end to the GND pin on the accelerometer. Then using a space on the breadboard in the same row as the GND pin of the accelerometer, place the end of a second jumper wire. The other end of that second jumper wire will go into the GND pin of the gyroscope. It'd be best to place the end of the second jumper wire in a space directly next to the one of the accelerometer. However, if it's any space of that row, it should technically work the same.
In the photo to the right, you can see how I connected the wires in a row.The photo to the left shows just the general view of all the wires I used to connect the pins.
I didn't solder anything. Was going to save that until the end.
So yea, that was one cool and usefull trick I learned!
Anyways, here's the code I used:

BY THE WAY.
I have stopped using Arduino as the basis of my Intel project. Instead, I will be using Texas Instrument's Sensor Tag product.
