Find $\left \lceil \frac{12}{7} \cdot \frac{-29}{3}\right\rceil - \left\lfloor \frac{12}{7} \cdot \left \lfloor \frac{-29}{3}\right \rfloor \right \rfloor$.

12/7  *  -29/3    =  -116/7  ≈  -16.xxx

Ceiling  -16.xxx =  -16

 

And

 -29/3   = -9.xxx 

Floor  -9.xxx   = -10

So

12/7 * -10  =  -120/7  = - 17.xxx

Floor  =   -17.xxx   =  -18

So

 

-16  -  (-18)   =  

 

-16  +  18  =
