       $\lfloor 3.1\rfloor$
       $\lfloor 3.9\rfloor$
       $\lfloor -3.1\rfloor$
       $\lfloor -3.9\rfloor$
b. Bepaal:
       $\lceil 3.1\rceil$
       $\lceil 3.9\rceil$
       $\lceil -3.1\rceil$
       $\lceil -3.9\rceil$

Uitwerking

       a. $\lfloor 3.1\rfloor =3$
           $\lfloor 3.9\rfloor =3$
           $\lfloor -3.1\rfloor =-4$
           $\lfloor -3.9\rfloor =-4$
       b. $\lceil 3.1\rceil =4$
           $\lceil 3.9\rceil =4$
           $\lceil -3.1\rceil =-3$
           $\lceil -3.9\rceil =-3$

Opdracht 2

a. Bepaal: $\lfloor -5.1\rfloor +\lceil 7.1\rceil$
b. Bepaal: $\lceil -7.7\rceil +\lceil 7.1\rceil$
c. Bepaal: $\lfloor 5.1\rfloor +\lfloor 10.8\rfloor$
d. Bepaal: $\lfloor 13.5\rfloor +\lceil 0.8\rceil$

Uitwerking

       a. $\lfloor -5.1\rfloor +\lceil 7.1\rceil =-6+8=2$
       b. $\lceil -7.7\rceil +\lceil 7.1\rceil =-7+8=1$
       c. $\lfloor 5.1\rfloor +\lfloor 10.8\rfloor =5+10=15$
       d. $\lfloor 13.5\rfloor +\lceil 0.8\rceil =13+1=14$
