"What is nine minus five?"

Translation: Berapa sembilan kurang lima?

[caesar_solid]

Shouldn't "Sembilan kurang lima sama dengan apa?" be accepted?

[AbdullahAAK]

Whenever we are talking about numbers, apa becomes berapa. Similarly whenever we talking about humans, apa becomes siapa

[WayneLunde]

Sebilan kurang lima sama dengan berapa

[MichaelG.845143]

That was my answer as well (with the correct spelling 'sembilan', tho), but it was flagged as wrong.
