MS Calculator (Android Only) by David J. Greene Mixed Media DOWNLOAD

Turn a 4×4 magic square into a memorable moment: your audience chooses a number, and every row, column, and diagonal adds up to it. MS Calculator by David J. Greene is an Android-only download disguised as a calculator, doing the calculations while you focus on your presentation.

Present the effect as mental magic or as a feat of mathematics. Two included presentations give you different ways to introduce it, from a motivational talk to a comedy routine.

• Android calculator disguise: Bring the app into play as a calculator while it handles the calculations.
• Two presentation options: Choose a motivational-speaking presentation or a comedy-focused presentation, each with its own reason to use the app.
• Two formulas: Use the separate formulas in the app for repeat performances.
• Digital download: MS Calculator is currently available for Android only.

Keep this magic square routine ready for a performance whenever the moment arises, and let your choice of presentation shape whether the audience sees a mathematical feat or mental magic.
