Exact vs. Approximate Values
Back
Exact values are precise representations (e.g., fractions, surds like √2, or π), whereas approximate values are rounded decimals (e.g., 3.14). In modeling, exact values are preferred for intermediate calculations to avoid rounding errors.
Front
Scientific Notation
Back
A way of writing numbers that are too big or too small in the form a × 10^k, where 1 ≤ a < 10 and k is an integer. This is essential for handling very large or small quantities efficiently in calculations.

Arithmetic Sequence Definition
Back
A sequence of numbers where the difference between consecutive terms is constant. This difference is called the common difference (d). Example: 2, 5, 8, 11... where d = 3.
Front
Geometric Sequence Definition
Back
A sequence where each term after the first is found by multiplying the previous term by a constant called the common ratio (r). Example: 3, 6, 12, 24... where r = 2.

Sigma Notation (Σ)
Back
The symbol Σ (capital sigma) is used to represent the sum of a sequence of terms. It allows for the concise representation of series, such as the sum of the first n integers.
