Submission Instructions:

- You must submit your assignment as a single pdf or .doc file:

• Include your code as an appendix; code should be copied and pasted and not submitted as a screenshot. Code must be properly formatted.
• Be sure that images are not high resolution or else there may be problems uploading your assignment.

- Organize your submission in the order that the questions are asked.

In this assignment, you will create a "10-key" calculator in android studio and Kotlin.

In android studio create a simple calculator app. It should replicate the functionality of the calculator found here: http://www.math.com/students/calculators/source/basic.htm?

The buttons included should be:

Number Keys: "1", "2", "3", "4", "5", "6", "7", "8", "9", "0"

Operation Keys: "+", "-", "*", "/"

Other Keys: "=", "CLEAR",

The CLEAR key should clear out the screen and everything in memory.

The = key will apply the operations and give the result.

Additionally, your calculator should have the following keys:

A DEL key which is the same as "backspace" and will remove the last character on the screen.

A "." key should indicate a decimal.

Deliverables You should submit a single document that contains the following:

1. An explanation of your application (like a simple user manual highlighting its features -- here is a good example)
2. Screenshots of your application showcasing its features.
3. A copy of the Kotlin code you've written in an appendix.
