Is my approach for calculator project going to work?

Hi all campers!

I’m trying to pass my calculator project on Front-end libraries curriculum these days.
I’m stuck on two test so far. I have looked for other posts here however I’m not sure my way of approach to this problem is working.

this is my project link and you can see I passed 14 test for now.
Do i need to change the way to solve problems ? Can you suggest me something new or give me some advices?

Thank you in advance!

Thank you @camperextraordinaire! I’ve solved problems yesterday and didn’t add comment about it because I thought my post hasn’t been read. :smiley: ha ha . Thank you for checking mine anyway! Even I’ve passed the tests it was a long journey almost Odyssey
