    Logarithms answer the question: “How many times do you have to multiply a base number (the number below the log) with itself to get the number within the brackets?”. Usually just saying log means log10, since we use the ten numerals 0 to 9 in our everyday lives.

    So log10 (1000) equals 3 because you have to multiply 10 by 10 by 10 to get 1000, that’s three tens.

    log2 (256) equals 8 because when you start at 1 and double it 8 times, it becomes 256.

    ln is the natural logarithm, equal to loge or log2.718…. It works the same as the rest, but it’s useful since e is used in some math equations representing some real world scenarios.
