- Freeway Park, officially known as Jim Ellis Freeway Park, is an urban park in Seattle, Washington, United States, connecting the city’s downtown to the Washington State Convention Center and First Hill. The park sits atop a section of Interstate 5 and a large city-owned parking lot; 8th Avenue also bridges over the park. An unusual mixture of brutalist architecture and greenery, the 5.2-acre (21,000 m2) park, designed by Lawrence Halprin’s office under the supervision of Angela Danadjieva, opened to the public on July 4, 1976, at a cost of $23.5 million. A later addition to the park opened in 1982 winds several blocks up First Hill, with a staircase and wheelchair ramp.

In mathematics, the logarithm is the inverse function to exponentiation. That means that the logarithm of a number x to the base b is the exponent to which b must be raised to produce x. For example, since 1000 = 10^3, the logarithm base 10 of 1000 is 3, or log10 (1000) = 3. The logarithm of x to base b is denoted as logb (x), or without parentheses, logb x, or even without the explicit base, log x, when no confusion is possible, or when the base does not matter such as in big O notation.
