Arithmetic Operators

Part of the Fundamentals section of Coddy's Ruby journey — lesson 11 of 88.

Ruby provides arithmetic operators to perform mathematical calculations on numbers. These operators work with both integers and floats, allowing you to build expressions just like you would in regular math.

The basic arithmetic operators in Ruby are:

`+`	Addition
`-`	Subtraction
`*`	Multiplication
`/`	Division
`**`	Exponentiation (power)

Here's how you can use these operators:

sum = 10 + 5        # 15
difference = 10 - 3 # 7
product = 4 * 6     # 24
quotient = 20 / 4   # 5
power = 2 ** 3      # 8 (2 to the power of 3)

One important detail: when dividing two integers, Ruby performs integer division and returns only the whole number part. For example, 7 / 2 returns 3, not 3.5. To get a decimal result, at least one number must be a float: 7.0 / 2 returns 3.5.

Challenge

Easy

You are provided with the following variables:

base = 5
height = 12

Calculate and display the following values, each on a separate line:

The sum of base and height
The result of height minus base
The product of base and height
The result of height divided by base (integer division)
The value of base raised to the power of 3

Cheat sheet

Ruby provides arithmetic operators to perform mathematical calculations:

`+`	Addition
`-`	Subtraction
`*`	Multiplication
`/`	Division
`**`	Exponentiation (power)

Examples:

sum = 10 + 5        # 15
difference = 10 - 3 # 7
product = 4 * 6     # 24
quotient = 20 / 4   # 5
power = 2 ** 3      # 8

Integer division: When dividing two integers, Ruby returns only the whole number part. For example, 7 / 2 returns 3. To get a decimal result, at least one number must be a float: 7.0 / 2 returns 3.5.

Try it yourself

# Variables are provided
base = 5
height = 12

# TODO: Write your code below to calculate and display:
# 1. The sum of base and height
# 2. The result of height minus base
# 3. The product of base and height
# 4. The result of height divided by base (integer division)
# 5. The value of base raised to the power of 3
