Division and Modulo Operations

Division and modulo operations are mathematical operations used to perform calculations involving numbers. Here's an explanation of these operations:

Division is the process of dividing one number by another to find the quotient or the result of the division. The division operator is typically represented by the symbol "/". For example, in the expression "10 / 5", 10 is divided by 5, resulting in a quotient of 2.

Modulo is the operation that calculates the remainder when one number is divided by another. The modulo operator is typically represented by the symbol "%". For example, in the expression "10 % 3", 10 is divided by 3, resulting in a remainder of 1.

Let's look at some examples to further illustrate these operations:

1. Example 1: - Expression: 5 mod 2 - Calculation: 5 divided by 2 equals 2 with a remainder of 1. - Result: The modulo operation returns 1 as the remainder. - Calculation: 5 % 2 = 1. 2. Example 2: - Expression: 19 mod -12 - Calculation: 19 divided by -12 equals -1 with a remainder of 7. - Result: The modulo operation returns 7 as the remainder. - Calculation: 19 % -12 = 7. 3. Example 3: - Expression: 6 / 2(1+2) - Calculation: The expression can be simplified using the order of operations (parentheses first, then multiplication and division from left to right). - Simplification: 6 / 2(1+2) = 6 / 2 * (1+2) = 6 / 2 * 3 = 3 * 3 = 9. - Result: The division operation returns 9 as the quotient. - Calculation: 6 / 2(1+2) = 9. It's important to note that the order of operations is crucial when performing calculations involving division and modulo operations. Parentheses should be evaluated first, followed by multiplication and division from left to right.

I hope this explanation clarifies the concept of division and modulo operations. Let me know if you have any further questions!
