Evaluate \(\lfloor -4 -.5 \rfloor \cdot \lceil 4 +.5 \rceil \cdot \lfloor -3 -.5 \rfloor \cdot \lceil 3 +.5 \rceil \cdot \dots \cdot \lfloor -.5 \rfloor \cdot \lceil .5 \rceil\)
The floor function means round down to the nearest integer
The ceiling function means round up to the nearest integer.
For example:
\( \lfloor -4 -.5 \rfloor =\lfloor -4.5 \rfloor =-5\\ \lceil 4 +.5 \rceil =\lceil 4.5 \rceil =5\\ \)
Can you take it from there?
