Why should you take this course?

Inequalities and simultaneous equations are fundamental tools in algebra that you'll find useful in many areas of life. Here's why they're important:

Inequalities:

Modelling real-world scenarios: Inequalities help represent limitations or boundaries in situations. For example, you might use an inequality to figure out how many hours you need to work to make a certain amount of money, considering your hourly wage.

Making decisions: Many choices involve restrictions. Inequalities help you analyse those restrictions and find the best option within those limits.

Simultaneous Equations:
Finding relationships between unknowns: These equations are like puzzles where you have multiple clues to solve for multiple unknowns. They're crucial in various fields like physics (motion problems) or economics (supply and demand).

Problem-solving foundation: Solving simultaneous equations trains your logical thinking and lays the groundwork for more advanced math concepts.

In short, studying these topics equips you to:
Translate real-world problems into mathematical language
  • Analyse situations with limitations or multiple variables
  • Make informed decisions and solve complex problems
  • Even if you don't pursue a field heavily reliant on math, these skills will benefit you in various ways throughout your life.

Gilda Clark

UniCourse Mathematics Lecturer
Gilda has a BSc(Hons) in Mechanical Engineering and a degree in Mathematics, followed by two postgraduate qualifications (PGCE) in Mathematics Education in Secondary and in Further Education, followed by an additional postgraduate certificate in teaching advanced mathematics from MEI exam board, Further Mathematics Network and Warwick University.
She has completed her initial studies abroad and prior to working at Unicourse, Gilda has gained a vast experience in teaching and lecturing mathematics, at all levels, engineering mathematics, some engineering units including mechanics, engineering science and structural mechanics in civil engineering to A-level mathematics and engineering students at BTEC level 3, HNC, HND, as well as the general mainstream education in schools and colleges for almost 20 years. She has experience in delivering one-to-one mathematics tuition as part of the NTP( National Tuition Programme).
At Unicourse, she is responsible for creating and developing A-level mathematics resources for maths.unicourse.org, from writing interactive exercises, module outlines to producing videos based on her own materials.
