Perhaps because the other prominent use is on the buttons of every single calculator in the world.
- kps 14y agoI recall using × and ÷ in primary school, before the advent of portable calculators. I know that's mere anecdotal evidence, but I believe there do exist reliable documentary sources from that era.
