The typical spreadsheet, with its in-built mathematical functions and chart plotting facilities, can provide an interesting graphical interface for an insight into the solution of simple practical differential equations. This technique avoids problems that may present a difficulty to those students without certain mathematical tools, which can sometimes cloud the issue. The article explores simple equations such as the exponential decay function, a terminal velocity situation, and the more complex situations of the simple harmonic oscillator and damped oscillations. Microsoft Excel<sup>TM</sup> is used throughout, and the article gives a small tutorial on spreadsheets.
