# Adding Logarithmic Values - Calculator

Add logarithms: calculate plus with values on a logarithmic scale. Both values must have the same base of the logarithm, the result is calculated on the same scale. Up to 10 values can be added. Only positive values are allowed as input, the base must be larger than 1.

Example: the Richter scale for earthquakes has base 10. It seems to be unlikely that two earthquakes will occur at the same time and right next to each other. But if that were to happen and one earthquake was magnitude 6 and the other was magnitude 5, then the total magnitude would be 6.041.
