Please do not copy-paste my response.

Additive inverse turns subtraction into an addition of a negative number (its additive inverse)

ex: 2 - 1 becomes 2 + (-1)

in this case, he tried to turn the -4.4 into its additive inverse, which would be + (-4.4) not just + 4.4. If you just swap the subtraction to addition you will get the wrong result.
