The overall description of it looks right, but in the picture the order of operations would be more like B, C, D, A not A, B, C, D
- Sharlin 6y agoYeah, that's a bit nonstandard order but multiplication, of course, is associative and commutative, so it doesn't really matter.
- JadeNB 6y agoIndeed—the advantage of doing it as you describe is that each new multiplication gives you a new digit that can be recorded immediately, rather than having to record the '2' from the 2 x 6 multiplication and later amend it to '5'.
