bitte, units nicht ones. Unless you're talking to a very small child.

Is this a BE/ AE difference? I remember learning about the ones column in school - it sounds right to me.

probably yes. Is this the infamous "New Math"? Apologies Sally!

Considering that I've been living in Germany for 20 years & my A.English has gone to he.., I did google this & did receive lots of replies regarding math books & children's education using "ones column", so obviously, Americans do use it (and have been for 30+ years, considering when I visited school)! But I am always open for criticism!

I found that one in a maths test.. (AE)
