Topic: Math education idea: instead of teaching kids addition, subtraction, multiplication, and division...

Just teach them addition and multiplication. You don't need subtraction: instead of subtracting, just add a negative number. Instead of, say, 5-3=2, you just make it be 5+(-3)=2. Same for division. Instead of 10/5=2, just do 10*.2=5

That way the time teaching arithmetic can be cut in half.

Next you'll be advocating use of the damn metric system..

the operations can be further reduced to mere counting.

Why not teach them only half of the numbers? Say, just the odd ones. That would cut time in half again!

Please express directly and concisely how the imperial system is any better than the metric system.

Nonsense. My car gets forty rods to the hogshead and that's the way I likes it, dagnabbit.
