**Algebra - Leaving Cert Ordinary Level**

In this lesson we will cover Leaving Cert Ordinary Level Algebra.

We will go through the following:

- Changing the subject of a formula
- Quadratics
- Solving Equations
- The Quadratic formula (−b formula)
- Solving simultaneous equations in two variables
- Solving linear and non-linear simultaneous equations
- Inequalities

There are detailed interactive tutorial videos where students are guided through the correct solutions to past leaving cert ordinary level paper questions.

Students can test their understanding with our algebra quiz. The quiz questions are taken from leaving cert ordinary level past papers, which helps to familiarize students with the style of the questions that will be presented to them in the leaving cert.

All living organisms can be classified into five different groups - these are called the '5 Kingdoms of Life'. Two of these groups are animals and plants; the other three groups - monera (bacteria) , protista and fungi - are microorganisms. Microorganisms are living organisms that are so small that we can't see them with the naked eye - we need a microscope to see them. These tiny creatures dominate the planet and we must aim to have a good understanding of the different types of them, their structure, what they eat, how they reproduce and examples of ones that are both good and bad for us.
