Is there a way to subtract a constant value from the values in an array?

Is there a way to subtract a specific number from the values in an array?

I’ve been suffering with pricing for 3 days now.

These are the values I received with ‘parseJSON’ - ‘array aggregator’.

I took the minimum value of these prices and designated it as ‘referencePrice’.

I then subtracted the ‘referencePrice’ from the rest of the prices and added the price of buying the option.

After 3 days of agonizing over this, I wrestled with YouTube, the community, and ChatGPT, but nothing satisfied me.

I finally saw a glimmer of hope that I could do it 50% with an iterator, but gave up when I saw it was eating 7 operations in one run.

Is there anyone out there who can help me out?
