2.36 = -logx
solve for x

Here's what you have to keep saying to yourself until it carves a new
groove into your brain and you don't have to think about it any more:

             " log(x) = the power that 10 must be raised to
                            in order to wind up with 'x'. "

You said    2.36 = -log(x)

Multiply each side by -1 :    log(x) = -2.36

Now translate it into the mantra:

     The power that 10 must be raised to
     in order to wind up with 'x' is  -2.36 .

Do you see what that means ? ! ?

If the power that 10 must be raised to in order to wind up with 'x'
is  -2.36,  then all you have to do to find 'x' is raise 10 to the power
of  -2.36  !    You can do that with about 4 clicks on your calculator.

   10^(-2.36) = 0.004365... (rounded)

And if you don't quite believe it, it's even easier to check it.
Punch  " 0.004365 " into your calculator, and then touch the
"  10^x " key, and something very close to  -2.36  will pop up
right there, before your wondrous eyes.

Ibelieve that c. recording would work best.
