Reducing balance loans, annuities and investments
General Maths Units 3 and 4 (2023+)
Introduction
This is the first in a new section of videos as part of the Year 12 General Maths (Units 3 and 4) course relating to Financial Mathematics. The full title of the work is ... and wait for the length of this title ... "Combining linear and geometric growth or decay to model compound interest investments with additions to the principal". So ... this video will recap the work from all of Chapter 7 (from the Cambridge textbook series) and then look at how we can add payments by making additions to the principal. It basically models real worlds examples! There are lots of worked examples which highlight how it might be used. All theory is explained in an easy to understand way.
