So I thought about this and I think it is actually
1.32
₁42
And the small 1 before 42 is that 1 you make when you add the tens digit in an addition. However there should not be another tens digit involved, and also 0.32+0.42 is 0.74 and not 0.64, and also I think this started as a multiplication.
Regarding the 1.80, I also thought about this but I got no fucking clue.
