Can you use clear and specific math language instead of our analogy of apples and pears? In other words, how can you revise your rule so anyone can follow it?

For topic D the rule I came up with was you always have to line up your digits in an algorithm. Or you can think about it as apples to apples.

I agree with you because if you don't line the midgets up you can add hundredths to thousandths and get the wrong answer.

(Topic D) When adding, if your answer equals more than ten, then you shift it up a place value.

When you multiple decimals by 10, 100, or 1,000 you move the decimal point once, twice, or three times to the right - 1 time for each zero.
