Basic Arithmetic Operations and Equations

The video tutorial explains the concept of equations, focusing on addition and subtraction. It demonstrates how to determine if equations are true or false by manipulating numbers and checking the equality of both sides. The tutorial provides examples of both addition and subtraction equations, illustrating the process of adjusting numbers to maintain balance and verifying the results.

What is a key component of an equation?

• A multiplication sign

• A greater than sign

• A division sign

• An equal sign
