I am so confused on their thought process. Like, I understand making mistakes, wrong operations, misunderstanding the question... but where did their numbers even come from?

1.32 + 1.42?

Where did the 1.42 come from?

And 43.80? Where is that from? Is it from the 42? Then where did the additional 1.80 come from?

    Best I can figure is that the 1.42 was written as 42 with a superscript ¹ fron the line below (as a tens marker when adding 6 and 8)

    43.80 might have come from multiplying 1.32 by 4 but forgetting to do the 3?

    They did 4x3 is 3, instead of 12. This is how they ended up $9 short on the final answer.

    I'm guessing they did the 4 x 3, noticed they had to carry, accidentally wrote the carry in the wrong column, then immediately went and added that carry to their leftover 2, thus only counting 3 in total.

    I think it started as 1.32 x 42, which they tried to solve as 2 x 1.32 (2.64) + 40 x 1.32 (they started correctly with .80 + ..., but I can't figure out how they mangled the second half). Anyway, 2.64 + .80 carries 1, which is the small 1 to the left of the 42.
