I would also like to know this. In the model Builder, I have calculated the equation foe NDVI for landsat images. But for some reason the keep getting error messages saying "Divided by Zero". Im not too sure what this means. The equation is of course (B4-B3) / (B4+B3). Any help would be great!

you need to use conditional statement: b4+b3 could equal zero so there is a possible division by zero!!! that is the "divided by zero" message.
