Exploring Adding and Subtracting Rational Expressions

The video tutorial covers solving one and two-step equations, including handling fractions and more complex equations. The teacher demonstrates solving techniques, emphasizing understanding over using apps for answers. Students are encouraged to solve problems independently and check their work using apps only for verification. The tutorial includes examples and different methods to solve equations, allowing students to choose their preferred approach.

What is the teacher's policy on using apps to solve equations?

• Apps can be used during exams.

• Apps should only be used to check answers, not solve problems.

• Apps are encouraged for solving all homework.

• Apps are not allowed at all.
