Brainlet here. I've decided to redo mathematics from pre-algebra. I'm reading Algebra by I.M. Gelfand and A.Shen. Came across this:
>After we get this zero, we keep "4" in mind because 8+8+8+8+8 = 40. To get the next zero in the ''tens place" from this "4" , we need to add at least two 8's since 4 + 8 + 8 = 20.
This
>we keep "4" in mind because 8+8+8+8+8 = 40
doesn't make sense to me. HELP
