# Math

Word problems are the bane of most math students, and why not. This is where mathematics, language arts, logic and the real world all intersect.

## Financial Ratios

Current Ratio
The ratio of current assets to current liabilities. This indicates the ability to pay it's current debts. You want a ratio of 1 or better.
Price to free cash flow

## Benford's Law

Benford's Law (also known as the first digit law) states that the first digit from most real life data follows a logarithmic distribution. This means that the first digit will be 1 30% of the time, 2 18% of the time, and so on to 9 appearing 5% of the time. This can be used as a good check to see if the data that you are using is biased or not.

## Polynomial and Rational Functions

Completely analyse functions to degree 5 Use synthetic division to factor functions

## Data Visualization

The students should be familiar with bar charts, pie charts, scatter plots, stem and leaf plots, Box and Whisker plots and histograms, both how to produce them and how to extract data from them. They should also know when to use each, and when not to. Shodor interactives has a number of activities on various graphs and charts

A quadratic equation is a second order (the highest power of the variable is 2) polynomial equation of 1 variable. It is typically written either as $y = ax^2 + bx +c$ or $y = a(x+k)^2 +c$ When graphed, it forms a parabola, with a single vertex (maximum or minimum point) and 0, 1, or 2 real roots (points where the graph crosses the x axis). In real life, we find this equation when dealing with ballistics, engineering, and optics. It also turns up in economics.
