Tessellations aren’t just eye-catching patterns—they can be used to crack complex mathematical problems. By repeatedly reflecting shapes to tile a surface, researchers uncovered a method that links ...

Mathematical models are a way to attempt to predict the probable outcome of a complex situation. From climate, stock market and physics models, you can use mathematical formulas to determine a range ...

Excel's basic formulas work fine for simple calculations, but they quickly become cumbersome when you're dealing with complex data analysis. You end up with nested functions that are hard to read, ...
