what are they asking for?
​

Answer 1

We want to study a general product, and find information about the ones place.

We will see that the ones place is always zero.

We have the expression:

10×?

Where ? can be any number between 1 and 9 (only whole ones)

What is true about the digit of the ones place (the first digit at the left of the decimal point) in each product?

Let's give ? some different values and see what happens:

10×1 = 10

10×2 = 20

10×3 = 30

etc...

We can see that the ones place will always be equal to zero.
