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
-16 - (-18) =
-16 + 18 =
2
