Evaluate \(\lfloor -4 -.5 \rfloor \cdot \lceil 4 +.5 \rceil \cdot \lfloor -3 -.5 \rfloor \cdot \lceil 3 +.5 \rceil \cdot \dots \cdot \lfloor -.5 \rfloor \cdot \lceil .5 \rceil\)

Here is my attempt:

 

[-25 * -16 * -9 * -4 *-1 *- 1] =14,400

How about you tell me what    \(\lfloor -7.2 \rfloor \)     is and why?

Yes it is so

I do not like this question much but I think this is what is meant.

 

-5*5     *      -4*4       .....      -1*1

-25      *         -16    *   (by extension)   -9*-4*-1     =    - 25*16*9*4*1  =   -14400

 

If you had looked properly at guest's answer maybe you could have found their little error.   wink
