Yes, of course, I do know that. It's not what I meant. Suppose we expand that first example. I would write: 3(x + 5) = 3x + 3⋅5 The notation I'm talking about

Suppose we expand that first example.
I would write: 3(x + 5) = 3x + 3⋅5
The notation I'm talking about writes: 3(x + 5) = 3x + 3(5)
It's that 3(5) instead of 3⋅5 I'm talking about.
- zodiac 6y agoI prefer to use a dot like you, but find calculations like "let x=5, then 3(1+x) = 3(1+5) = 3(6) = 18" acceptable, because each equation is just a lock substitution
