Hi all, I grew up in a jurisdiction that required 12 year olds learn binary number arithmetic - for additions and subtractions - using standard mathematics concepts of carry and borrow. It was geared towards forcing students to learn that the concept or carry and borrow can be stretched beyond the decimal systems. (no two's complements here)
I remember binary subtractions were very tricky to master even for gifted students. I never passed in binary number arithmetic because I couldn't do subtractions consistently. That was back in the early 1990s.
Then I immigrated to New Zealand and continued my high school years there, and had discovered that binary number arithmetic wasn't a topic in New Zealand secondary Maths curriculum. And probably for most other countries too.
So was it always a niche or difficult topic in Maths education, and not many countries' education systems taught/teach it? Thanks.
PS: just to clarify binary arithmetic wasn't taught for computing or early computer engineering, it was basically about teaching number systems and getting students to become flexible with arithmetic techniques when the base is no longer 10.
