also not sure what the second part of your question is, but hopefully this still helps.

The correct answer to this question is Carlos's first error in step 2.

What are friendlier numbers?

The friendly number addition approach facilitates working with large numbers. This is due to the fact that we are, in essence, decomposing the problem into simpler parts.

When we talk about friendly numbers, we mean a number that is simple to use. For instance, quantities of 100 are friendly because we can easily add to or subtract from them.

In another word friendlier numbers are those numbers that are easy to calculate if you want to divide 8 by 3 then it is difficult but by 8 by 10 then it becomes easy so 10 will become a friendlier number.

In the given question Carlos's first error is in step 2 because it is not matching with the distributive property.
