Math Review: Geometry, Financial Math, and Equations

A set of vocabulary flashcards covering the key terms, formulas, and concepts from lecture notes on geometry, financial mathematics, and linear equations.

Pythagoras Thecrom

The formula $a^2 + b^2 = c^2$ used to calculate side lengths in triangles.

Interest ($I$)

The extra money earned or charged.

Principal ($P$)

The starting amount of money.

Rate ($r$)

The percentage charged or earned each year.

Time ($t$)

How long the money stays in the account or loan.

Simple Interest Formula

The formula given by $I = P \times r \times t$.

Compound Interest Formula

The formula $A = P(1 + r)^n$, where the total interest earned is calculated as $I = A - P$.

Depreciation Formula

The formula $A = P(1 - r)^n$ used to calculate decreasing value over time.

Linear Equation Solving

The process of performing inverse operations on both sides to solve for a variable, such as solving $3x + 5 = 17$ to find $x = 4$.
