Page 2: Annual Effective Interest Rate Calculations

This section provides comprehensive calculations for converting various periodic interest rates to annual effective rates using standardized formulas.

Vocabulary: Annual Effective Rate - The actual annual rate of return accounting for compound interest effects

Example: Monthly rate of 0.3% converts to 3.65% annual effective rate using (1.00312(1.003^12-1)×100

Highlight: The formula (1+r(1+r^n-1)×100 is consistently used where r is periodic rate and n is number of periods per year

Page 1: Investment Calculations and Interest Rates

This page focuses on calculating compound interest across different time periods and investment scenarios. The calculations demonstrate how to handle varying interest rates and investment amounts over time.

Example: £70 invested at 2% per year for 6 months yields £70.70 using the formula: 70 × 1.02^1/21/2²

Highlight: Multiple investments are tracked over time with different interest rates 55% per year, 2% per half-year, 1% per month

Definition: Annual effective rate converts different periodic rates into a comparable annual basis

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

Just amazing. Let's me revise 10x better, this app is a quick 10/10. I highly recommend it to anyone. I can watch and search for notes. I can save them in the subject folder. I can revise it any time when I come back. If you haven't tried this app, you're really missing out.

This app has made me feel so much more confident in my exam prep, not only through boosting my own self confidence through the features that allow you to connect with others and feel less alone, but also through the way the app itself is centred around making you feel better. It is easy to navigate, fun to use, and helpful to anyone struggling in absolutely any way.

The app's just great! All I have to do is enter the topic in the search bar and I get the response real fast. I don't have to watch 10 YouTube videos to understand something, so I'm saving my time. Highly recommended!

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7. I didn’t even know about this app three days until the exam and it has helped A LOT. Please actually trust me and use it as I’m sure you too will see developments.
