Mathematica does not evaluate cell to a numerical value

I simply want to calculate the log[2] e. g. in Mathematica and the result I get is log[2]. The same happens with sin and so on. But it calculates something like 5*5. What is the reason for this? I can't find anything in the settings and I tried some commands too (like calculate).

Solution

  • The first word of the function must be capitalized log -> Log

    Log[1.9999999999000005*^-13] -29.240459028412648`
