Caption: Antilog or Anti-logarithm
Text: The logarithm of a number is the exponent by which another fixed value, its base, must be raised to produce that number. For example, the logarithm of 1000 to base 10 is 3, because 1000 is 10 to the power 3 1000 = 10 × 10 × 10 = 103. More generally, if x = by, then y is the logarithm of x to base b, and is written y = logb(x), so log10(1000) = 3.
The anti-logarithmn converts the logarithm back into the original value. So anti-log10(3) = 1000.
