Ruby - Arithmetic operators

1. Introduction

Ruby offers a variety of arithmetic operators to perform common mathematical operations. These operators are essential tools when you need to manipulate numeric data, whether they are integers or floating-point numbers.

2. Program Steps

1. Initialize sample variables.

2. Apply and demonstrate the arithmetic operators on the initialized variables.

3. Code Program

# Initialize sample variables
a = 15
b = 4
# Addition
addition_result = a + b
puts "Addition: #{a} + #{b} = #{addition_result}"
# Subtraction
subtraction_result = a - b
puts "Subtraction: #{a} - #{b} = #{subtraction_result}"
# Multiplication
multiplication_result = a * b
puts "Multiplication: #{a} * #{b} = #{multiplication_result}"
# Division
division_result = a.to_f / b.to_f # Convert to float for precise division
puts "Division: #{a} / #{b} = #{division_result}"
# Modulus
modulus_result = a % b
puts "Modulus: #{a} % #{b} = #{modulus_result}"
# Exponentiation
exponentiation_result = a ** b
puts "Exponentiation: #{a} ** #{b} = #{exponentiation_result}"

Output:

Addition: 15 + 4 = 19
Subtraction: 15 - 4 = 11
Multiplication: 15 * 4 = 60
Division: 15 / 4 = 3.75
Modulus: 15 % 4 = 3
Exponentiation: 15 ** 4 = 50625

Explanation:

1. The Addition (+) operator adds two numbers.

2. The Subtraction (-) operator subtracts the right operand from the left.

3. The Multiplication (*) operator multiplies two numbers.

4. The Division (/) operator divides the left operand by the right. Note that integer division will round down the result. For a precise division result, you should convert the numbers to floats.

5. The Modulus (%) operator returns the remainder of the division of the left operand by the right.

6. The Exponentiation () operator raises the number to the power of the right operand.
