This is my proposal for how the numerical question function and interface should be improved.
[_]Allow evaluation of expressions
Checking this would accept 5/2 0.5*5 5^2/2 5^(5-3)/2 25*10^-1 sqrt(25)/2
[_]Allow fraction type 2 1/2 as 2.5
[_] Translate "½" as "+.5" but give warning "Avoid ½ character in numerical expressions!"

[_] differentiated unit feedback, which is all of:
All of: [_] feedback for lacking unit [_]Feedback for accepted UNIT but wrong number
[_] feedback for "possibly right number" if unit is adjusted
Unit: [ ] (optional)
Should accept arrays like kg, kilogram, kilograms , kilogramme
Alternative Units: Multiplier:[ ] Unit: [
Should possibly give feedback for misspelling including case errors m milli M Mega
Multiplier: Unit:
