# Simple calculator

This a problem set for you to work through [1]

This is a problem set. Some of these are easy, others are far more difficult. The purpose of these problems sets are:

1. to build your skill applying computational thinking to a problem
2. to assess your knowledge and skills of different programming practices

## What is this problem set trying to do

In order to complete this problem set, you should have a good understanding of Functions.

## The Problem

1. Write a function that accepts 2 numbers and returns the sum
2. Write a function that accepts 2 numbers and returns the quotient
3. Write a function that accepts 2 numbers and returns the product
4. Write a function that accepts 2 numbers and returns the difference

## Unit Tests

• User Input: sum(12,33)
• Expected output: 45
• User Input: diff(25,5)
• Expected output: 20
• User Input: quot(30,2)
• Expected output: 60
• User Input: prod(30,2)
• Expected output: 15

## How you will be assessed

Scope

• To what extent does your code implement the features required by our specification?
• To what extent is there evidence of effort?

Correctness

• To what extent did your code meet specifications?
• To what extent did your code meet unit tests?
• To what extent is your code free of bugs?

Design

• To what extent is your code written well (i.e. clearly, efficiently, elegantly, and/or logically)?
• To what extent is your code eliminating repetition?
• To what extent is your code using functions appropriately?
