Topic 1: Number and Algebra

THE BIG PICTURE. AI Topic 1 emphasises applied algebra — scientific notation, sequences and series, financial mathematics, and basic exponents/logs. HL extends to complex numbers (light), matrix algebra, eigenvalues, and Markov chains. The GDC is used heavily; AI rewards clear technology use and clear interpretation of numerical results.

Sample Flashcards

$5{,}000 is invested at $4%$ p.a. compound interest, compounded quarterly. Find value after 3 years.

$FV = PV (1 + \frac{r}{100 k})^{k n}$ with $PV = 5000$ , $r = 4$ , $k = 4$ , $n = 3$ . $FV = 5000 (1 + \frac{4}{400})^{12} = 5000 (1.01)^{12} \approx 5, 634.13$ , i.e. $5{,}634.13. Compare with simple interest: $5000 \cdot (1 + 0.04 \cdot 3) = 5, 600$ , i.e.

A car is worth $25{,}000 and depreciates at $15%$ per year. Find its value after 4 years.

Depreciation = compound interest with negative rate. $Value = 25000 (1 - 0.15)^{4} = 25000 (0.85)^{4} \approx 25000 \cdot 0.522 \approx 13, 050.16$ , i.e. $13{,}050.16. The car retains about $52%$ of its value after 4 years.

Sample Key Terms

Scientific Notation

$a \times 1 0^{n}$ where $1 \leq ∣ a ∣ < 10$ and $n \in Z$ . Used to compactly express very large or very small numbers.

Percentage Error

$\frac{∣ v _{A} - v _{E} ∣}{v _{E}} \times 100%$ , where $v_{E}$ is the exact value and $v_{A}$ is the approximate. Always positive.

Arithmetic Sequence

Sequence with constant common difference $d$ . $u_{n} = u_{1} + (n - 1) d$ ; $S_{n} = \frac{n}{2} (u_{1} + u_{n})$ .
