FAQs on Ruby Programming Tutorial-3-Arithmetic Operators Video Lecture - Introduction to Coding with Ruby (in Hindi) - Back-End Programming
| 1. What are arithmetic operators in Ruby? |  |
Ans. Arithmetic operators in Ruby are symbols that perform mathematical operations on operands. These operators include addition (+), subtraction (-), multiplication (*), division (/), and modulus (%). They are used to manipulate numerical values in Ruby programs.
| 2. How do I perform addition and subtraction in Ruby? | |
Ans. Addition and subtraction in Ruby can be performed using the + and - operators, respectively. For example, to add two numbers, you can use the following syntax:
```
result = number1 + number2
```
To subtract one number from another, you can use:
```
result = number1 - number2
```
| 3. How can I multiply and divide numbers in Ruby? | |
Ans. Multiplication and division in Ruby can be done using the * and / operators, respectively. For example, to multiply two numbers, you can use:
```
result = number1 * number2
```
To divide one number by another, you can use:
```
result = number1 / number2
```
Note that division in Ruby returns a floating-point number if the operands are not integers.
| 4. What is the modulus operator in Ruby? | |
Ans. The modulus operator (%) in Ruby returns the remainder when one number is divided by another. For example, if you divide 5 by 2, the remainder is 1. Therefore, the expression `5 % 2` will evaluate to 1. Modulus is often used to check if a number is even or odd, as any even number modulo 2 will be 0, while any odd number modulo 2 will be 1.
| 5. Can I combine arithmetic operators in Ruby? | |
Ans. Yes, you can combine arithmetic operators in Ruby to perform more complex calculations. Ruby follows the standard order of operations, so expressions within parentheses are evaluated first, followed by multiplication, division, and modulus, and then addition and subtraction. For example, `result = (number1 + number2) * number3` will first add `number1` and `number2`, and then multiply the result by `number3`.
