JS Calculator - 13th bug. Anyone solved?

[ulugbek]

Hey there!

I’m bulding a JS calculator and trying to past the FCC test on it. But the FCC test is showing this error:

13. If 2 or more operators are entered consecutively, the operation performed should be the last operator entered (excluding the negative (-) sign.
    The sequence “5 * - 5” = should produce an output of “-25” : expected ‘-5’ to equal ‘-25’.

Here is my code: https://codepen.io/ulugbek/pen/KOmErL

Interesting enough, the FCC example has the same 13th bug right here: https://codepen.io/freeCodeCamp/full/wgGVVX

Anyone solved this issue? Please share your experiance.

Thanks!

Guys, I’m almost through with my JS calc but for one minor problem. It’s with user story #13 which states: 13. If 2 or more operators are entered consecutively, the operation performed should be the last operator entered (excluding the negative (-) sign. The sequence “5 * - 5” = should produce an output of “-25” : expected ‘0’ to equal ‘-25’ AssertionError: The sequence “5 * - 5” = should produce an output of “-25” : expected ‘0’ to equal ‘-25’ (excluding the negative (-) sign was not listed …

Also, loosely explain how your code works (mainly the part where the calculation happens [what function are we editing?]).

Here’s the logic of your code, as I see it working

• enter 5
  • currentComputation === ‘5’
• enter *
  • currentComputation === ‘0’
• enter -
  • currentComputation === ‘0 -’
• enter 5
  • currentComputation === ‘0 - 5’

And 0 - 5 === -5

Yes, I think I need to implement some logic to handle negative numbers.
