Addition (+) #<\/a><\/h2>\n\n\n\n

The addition operator (+) allows you to add two numbers. You can use it to calculate the total of numbers. For example:<\/p>\n\n\n

a = 10<\/span>\nb = 3<\/span>\nresult = a + b\n\nprint(result )<\/code><\/span>Code language:<\/span> Python<\/span> (<\/span>python<\/span>)<\/span><\/small><\/pre>\n\n\n
Output:<\/p>\n\n\n
13<\/span><\/code><\/span>Code language:<\/span> Python<\/span> (<\/span>python<\/span>)<\/span><\/small><\/pre>\n\n\n
Subtraction (-) #<\/a><\/h2>\n\n\n\n
The subtraction operator (-) allows you to subtract the second number from the first one. You can use it to calculate the difference between two values. For example:<\/p>\n\n\n
a = 10<\/span>\nb = 3<\/span>\nresult = a - b\n\nprint(result)<\/code><\/span>Code language:<\/span> Python<\/span> (<\/span>python<\/span>)<\/span><\/small><\/pre>\n\n\n
Output:<\/p>\n\n\n

Multiplication (*) #<\/a><\/h2>\n\n\n\n
The multiplication operator (*<\/code>) allows you to multiply two numbers. You can use it to calculate areas, scaling numbers, and perform financial calculations:<\/p>\n\n\n
a = 10<\/span>\nb = 3<\/span>\nresult = a * b\n\nprint(result)<\/code><\/span>Code language:<\/span> Python<\/span> (<\/span>python<\/span>)<\/span><\/small><\/pre>\n\n\n
Output:<\/p>\n\n\n
30<\/span><\/code><\/span>Code language:<\/span> Python<\/span> (<\/span>python<\/span>)<\/span><\/small><\/pre>\n\n\n
Division (\/) #<\/a><\/h2>\n\n\n\n
The division operator (\/<\/code>) allows you to divide the first number by the second one and return a float. You can use it to calculate the averages and perform financial calculations. For example:<\/p>\n\n\n
a = 10<\/span>\nb = 3<\/span>\nresult = a \/ b\n\nprint(result)<\/code><\/span>Code language:<\/span> Python<\/span> (<\/span>python<\/span>)<\/span><\/small><\/pre>\n\n\n
Output:<\/p>\n\n\n
3.3333333333333335<\/span><\/code><\/span>Code language:<\/span> Python<\/span> (<\/span>python<\/span>)<\/span><\/small><\/pre>\n\n\n
Floor Division (\/\/) #<\/a><\/h2>\n\n\n\n
The floor division operator ( \/\/<\/code> ) allows you to perform integer division and return a number without the decimal part. For example:<\/p>\n\n\n
a = 10<\/span>\nb = 3<\/span>\nresult = a \/\/ b\n\nprint(result)<\/code><\/span>Code language:<\/span> Python<\/span> (<\/span>python<\/span>)<\/span><\/small><\/pre>\n\n\n
Output:<\/p>\n\n\n
3<\/span><\/code><\/span>Code language:<\/span> Python<\/span> (<\/span>python<\/span>)<\/span><\/small><\/pre>\n\n\n
Modulus (%) #<\/a><\/h2>\n\n\n\n
The modulus operator (%<\/code> ) allows you to return the remainder of the division of two numbers:<\/p>\n\n\n
a = 10<\/span>\nb = 3<\/span>\nresult = a % b\n\nprint(result)<\/code><\/span>Code language:<\/span> Python<\/span> (<\/span>python<\/span>)<\/span><\/small><\/pre>\n\n\n
Output:<\/p>\n\n\n
1<\/span><\/code><\/span>Code language:<\/span> Python<\/span> (<\/span>python<\/span>)<\/span><\/small><\/pre>\n\n\n
You can use the modulus operator to check if a number is odd \/ even:<\/p>\n\n\n
a = 101<\/span>\n\nif<\/span> a % 2<\/span> == 1<\/span>:\n    print(f'{a}<\/span> is odd.'<\/span>);\nelse<\/span>:\n    print(f'{a}<\/span> is even.'<\/span>);<\/code><\/span>Code language:<\/span> Python<\/span> (<\/span>python<\/span>)<\/span><\/small><\/pre>\n\n\n
Output:<\/p>\n\n\n
101<\/span> is<\/span> odd.<\/code><\/span>Code language:<\/span> Python<\/span> (<\/span>python<\/span>)<\/span><\/small><\/pre>\n\n\n
You can also use the % operator to check whether a year is a leap year or not:<\/p>\n\n\n
year = 2024<\/span>\n\nif<\/span> (year % 4<\/span> == 0<\/span> and<\/span> year % 100<\/span> != 0<\/span>) or<\/span> (year % 400<\/span> == 0<\/span>):\n    print(f\"{year}<\/span> is a leap year.\"<\/span>)\nelse<\/span>:\n    print(f\"{year}<\/span> is not a leap year.\"<\/span>)<\/code><\/span>Code language:<\/span> Python<\/span> (<\/span>python<\/span>)<\/span><\/small><\/pre>\n\n\n
Output:<\/p>\n\n\n
2024<\/span> is<\/span> a leap year.<\/code><\/span>Code language:<\/span> Python<\/span> (<\/span>python<\/span>)<\/span><\/small><\/pre>\n\n\n
Exponentiation (**) #<\/a><\/h2>\n\n\n\n
The exponentiation operator ( **<\/code> ) raises the first number to the power of the second number:<\/p>\n\n\n
a = 10<\/span>\nb = 3<\/span>\nresult = a ** b\n\nprint(result)<\/code><\/span>Code language:<\/span> Python<\/span> (<\/span>python<\/span>)<\/span><\/small><\/pre>\n\n\n
Output:<\/p>\n\n\n
1000<\/span><\/code><\/span>Code language:<\/span> Python<\/span> (<\/span>python<\/span>)<\/span><\/small><\/pre>\n\n\n
You can use the exponentiation operator (**) in scientific and financial calculations. For example, you can use the exponentiation operator to calculate the compound interest:<\/p>\n\n\n
principal = 1000<\/span>\ninterest_rate = 0.05<\/span>\nyear = 2<\/span>\namount = principal * (1<\/span> + interest_rate ) ** year\n\nprint(f\"Total Amount: ${amount:,.2<\/span>f}<\/span>\"<\/span>)<\/code><\/span>Code language:<\/span> Python<\/span> (<\/span>python<\/span>)<\/span><\/small><\/pre>\n\n\n
Output:<\/p>\n\n\n
Total Amount: $1<\/span>,102.50<\/span><\/code><\/span>Code language:<\/span> Python<\/span> (<\/span>python<\/span>)<\/span><\/small><\/pre>\n\n\n
In this example, if you have $1,000<\/code> with 5%<\/code> interest rate, after 2 years, you’ll receive $1,102.50<\/code>.<\/p>\n\n\n\n
