Type 'Number' doesn't exist, only 'number' (not that it's the solution, but something you should know)

Once again: USE A SPOILER WHEN YOU POST CODE.

I put the flag on for you twice.

I also gave you a link to format properly your code.

• If you don't understand something, it is not an issue (= a bug in the kata), ask a question;
• Please use a spoiler flag when you post code somewhere
• Use markdown tags to format your code or it's not usable. Refer to the documentation about this and more: https://docs.codewars.com/training/troubleshooting/#post-discourse

Read the description again, 1 = 1

17935 # 1 + 7 = 3 + 5 // if the length is odd, you should ignore the middle number when adding the halves.
