Log[] in Mathematica is, by default, the natural logarithm (base e). The log() function on your calculator is most likely the common logarithm (base 10). On a calculator, the natural logarithm is probably ln(). You can use Log[] in any base by giving the base as the first argument. The common logarithm of x would be Log[10,x], for example, or you can be explicit to use the natural logarithm by specifying Log [E,x] Check the zoom level, which would be in a little bar at the bottom of your notebook. I suspect it is set to a very small value. Daniel
