+981 Find \(\left \lceil \frac{12}{7} \cdot \frac{-29}{3}\right\rceil - \left\lfloor \frac{12}{7} \cdot \left \lfloor \frac{-29}{3}\right \rfloor \right \rfloor\)
+23246 ceiling( 12/7 · -29/3 ) = ceiling( -16.57... ) = -16
floor( 12/7 · -29/3 ) = floor( -16.57...) = -17
-16 - -17 = -16 + 17 = 1
+36915 ceiling ( 12 x -29)/(7x3) = ceiling = -16
floor -29/3 = -10
floor (12/7 x -10) -18
-16 - - 18 = 2
