3. Importance of Calculations
Calculation is key to solving problems in mathematics and statistics.
Memory calculation: Using the calculator effectively to save time.
4. Memory Calculations
Use the memory function of the calculator (M+ for storing, M- for negative values, MRC for recalling).
Example of complex calculations and how to simplify using memory functions.
5. Syllabus Overview
Mathematics Syllabus Breakdown:
Focus on shortcut methods and efficient problem-solving techniques.
6. Time Value of Money
Concept: The idea that the value of money changes over time due to factors like inflation.
Key Terms:
Present Value (PV): The current value of money.
Future Value (FV): The value of money at a future date.
7. Interest Calculations
Simple Interest (SI): Calculated on the principal amount only.
Compound Interest (CI): Calculated on the principal plus previously earned interest.
Understanding how to calculate both SI and CI effectively using formulas.
8. Annuities and Their Applications
Annuity: A fixed amount paid regularly for a specified time.
Types of Annuities:
Ordinary Annuity: Payments made at the end of each period.
Annuity Due: Payments made at the beginning of each period.
Future Value of Annuity: Formula to calculate future value of regular payments.
Present Value of Annuity: Formula to calculate the present value of future annuity payments.
9. Effective Rate of Interest
The effective rate of interest takes compounding into account and is generally higher than the nominal rate when compounding occurs more than once per year.
Formula:
For effective rate: E = (1 + i/n)^(nt) - 1
Where i = nominal rate, n = number of compounding periods per year, t = number of years.
10. Depreciation
Concept: Value of assets decreases over time.
How to calculate depreciation using different formulas based on the method of depreciation chosen (straight-line, reducing balance etc.).
11. Valuation of Bonds
Bond: A debt security indicating a loan made by an investor to a borrower.
How to calculate the present value of a bond based on its future cash flows.
12. Investment Decision Making
How to decide between leasing and purchasing based on present value calculations.
Importance of comparing present value of cash inflows against cash outflows.
13. Exercises and Practice Questions
Go through previous years' papers to practice problems related to the above concepts.
Focus on understanding types of questions and applying the appropriate methods for solving them.
