Bug ID: 497580
Summary: Wrong result for calculations of the form a-b*c+d+e
Classification: Applications
Product: kcalc
Version: 24.08.3
Platform: Manjaro
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general

Target Milestone: ---
SUMMARY
Any calculation where there is a subtraction of a product as the second term
and two additions or subtraction follow is wrong. The problem only occurs after
a second addition, i.e. a-b*c+d is calculated correctly, but a-b*c+d+e is not.
The sign of "d" gets inverted.
STEPS TO REPRODUCE
1. Enter "1-1*1+1". Result: 1. Correct.
2. Enter "1-1*1+1+0" Result: -1. Wrong. +1 would be correct.
3. Enter "4-2*2+100+10". Result: -90. Wrong. kcalc calculates with the sign of
the last operand inverted.
OBSERVED RESULT
Wrong calculation results.
EXPECTED RESULT
Correct calculation results.
