Common and Natural Logarithm
Logarithm , the exponent or power to which a base must be raised to yield a given number. Logarithms of the latter sort that is, logarithms with base 10 are called common , or Briggsian, logarithms and are written simply log n. Invented in the 17th century to speed up calculations, logarithms vastly reduced the time required for multiplying numbers with many digits. They were basic in numerical work for more than years, until the perfection of mechanical calculating machines in the late 19th century and computers in the 20th century rendered them obsolete for large-scale computations. Logarithms were quickly adopted by scientists because of various useful properties that simplified long, tedious calculations.
