calculator behavior changed

iPhone 14 / iOS 18.2.1

Previously when using the Calculator on iOS, I could perform minus and
plus calculations without using the = button.  A [running total] would
display after each +/- use.

2365.23 + 1254.58 + [3619.81] 235.96 - [3855.77] 1479.99 = 2375.78

Now I must use the = button after every calculation to see the [running
total].  It's hard to keep a checkbook register correct if you can't
see the running total.  Hitting the = button after every number is
cumbersome when you're running through several pages.  The calculators
on my desktop computer and on the internet work as expected.

Does anyone else see this?  I looked for any options on the application
itself and in Settings to change this but to no avail.
