# Explain the concept of modular operations

**Question description**

**I have a specific section of a task that I'm working on and would like you to complete it. I need this in less than 12 hours, only bid if you can complete on time.**

C. Modular Operations: You want to explain the concept of modular operations to a middle school mathematics classroom, starting with a demonstration from clock arithmetic. Your explanation should include the following support:

• Appropriate examples for modular addition using positive integers

• Appropriate examples for modular addition using negative integers

• Appropriate examples for modular multiplication using positive integers

• Appropriate examples for modular multiplication using negative integers

• A sentence or two about the use of modular operations in real-world scenarios

1. Explain how you would discuss the following (*suggested length of 1–2 pages*) in the classroom setting:

a. Modular arithmetic and its relation to time

b. What is meant by 10 mod 6
