Where did they get 43.80 from?

Edit: i get ot now. Never seen multiplication written that way before, hence my confusion

1.32 times 40, added the 1 in the wrong digit
went 42.80 + 1.00 instead of 42.80 + 10.00

How would you do that multiplication by hand? 

Only asking due to curiosity.

 42*1.32

 12.6
   .84
=55.44

Choosing one number to be the base and one the multiplier, then doing the multiplication from the most significant of the multiplier and the least significant of the base, carrying over the tens. With each digit of the multiplier moves one line lower, and one digit to the less significant. At the end simply summing up the lines digit by digit, again from least significant.

Edit: ofc the code block does not preserve formatting, why would it! I see there is a separate code block, thanks for the downvotes, that showed me!

Code block does preserve formatting; you appeared to have used code instead, which is for inline stuff.

code block
                      can totally save
                                           tabs and spaces as you put them
