Hey! So, you’re learning about arithmetic operators<\/strong> in C#? Great choice! These operators are like the math tools you\u2019ll use every day while coding. They help you perform basic math operations like adding, subtracting, multiplying, and more.<\/p>

\u00a0<\/p>

What Are Arithmetic Operators?<\/h3>

In C#, arithmetic operators<\/strong> are used to perform calculations on numbers. If you\u2019ve used a calculator before, you\u2019re probably already familiar with these operations. In programming, they\u2019re used to handle numbers and values in a similar way.<\/p>

Let\u2019s go over each operator and see how it works.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

1. Addition (+)<\/strong><\/h3>

The +<\/code> operator is used to add two numbers together. It\u2019s just like the “plus” button on your calculator. For example:<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t
\n\t\t\t\t\t
\r\n\t\t\t
\r\n\t\t\t\t\r\n\t\t\t\t\tint sum = 5 + 3;  \/\/ sum will be 8\r\n\t\t\t\t<\/code>\r\n\t\t\t<\/pre>\r\n            <\/div>\r\n                \t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t
It adds 5<\/code> and 3<\/code> to get 8<\/code>.<\/p>
\u00a0<\/p>
2. Subtraction (-)<\/strong><\/h3>
Next up, we have the -<\/code> operator. It\u2019s used to subtract one number from another. Just like the “minus” button on a calculator. Here\u2019s an example:<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t                    
\r\n\t\t\t
\r\n\t\t\t\t\r\n\t\t\t\t\tint difference = 10 - 4;  \/\/ difference will be 6\r\n\t\t\t\t<\/code>\r\n\t\t\t<\/pre>\r\n            <\/div>\r\n                \t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t
It subtracts 4<\/code> from 10<\/code> to give you 6<\/code>.<\/p>
\u00a0<\/p>
3. Multiplication (*)<\/strong><\/h3>
The *<\/code> operator is used to multiply numbers. Think of it as the “times” button. Let\u2019s see an example:<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t                    
\r\n\t\t\t
\r\n\t\t\t\t\r\n\t\t\t\t\tint product = 4 * 3;  \/\/ product will be 12\r\n\t\t\t\t<\/code>\r\n\t\t\t<\/pre>\r\n            <\/div>\r\n                \t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t
It multiplies 4<\/code> by 3<\/code> to give you 12<\/code>.<\/p>
\u00a0<\/p>
4. Division (\/)<\/strong><\/h3>
Now, the \/<\/code> operator is for dividing numbers. Just like the “divide” button on a calculator. For example:<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t                    
\r\n\t\t\t
\r\n\t\t\t\t\r\n\t\t\t\t\tint quotient = 20 \/ 4;  \/\/ quotient will be 5\r\n\t\t\t\t<\/code>\r\n\t\t\t<\/pre>\r\n            <\/div>\r\n                \t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t
It divides 20<\/code> by 4<\/code>, and the result is 5<\/code>. Keep in mind, C# will perform integer division<\/strong> if both numbers are integers. So, if you divide 7 \/ 3<\/code>, you\u2019ll get 2<\/code> because C# will ignore the decimal part.<\/p>
But, if you want a more precise result (with decimals), you can use floating-point numbers<\/strong> (like float<\/code> or double<\/code>). Here\u2019s an example:<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t                    
\r\n\t\t\t
\r\n\t\t\t\t\r\n\t\t\t\t\tdouble preciseDivision = 7.0 \/ 3.0;  \/\/ preciseDivision will be 2.3333\r\n\t\t\t\t<\/code>\r\n\t\t\t<\/pre>\r\n            <\/div>\r\n                \t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t
\u00a0<\/h3>
5. Modulus (%)<\/strong><\/h3>
The %<\/code> operator is super handy! It\u2019s used to find the remainder of a division. For example:<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t                    
\r\n\t\t\t
\r\n\t\t\t\t\r\n\t\t\t\t\tint remainder = 7 % 3;  \/\/ remainder will be 1\r\n\t\t\t\t<\/code>\r\n\t\t\t<\/pre>\r\n            <\/div>\r\n                \t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
\n\t\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t
It divides 7<\/code> by 3<\/code>, but instead of giving the result of the division, it gives you the remainder. So in this case, 7 \u00f7 3<\/code> leaves a remainder of 1<\/code>.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
