Aber, wir wollen sachlich bleiben, mathematisch, informatisch, wie auch immer, ich mache weiter. 

1.) Rechne die Zahl in binaer Darstellung  in eine Dezimale Darstellung um
0010011100010011b 10003d
2.) Rechne die Zahl in dezimal darstellung in eine Binaerdarstellung um
37608 1001001011101000
3.) Addiere die drei Zahlen schriftlich
            29202
+           27875
+           19787
-----------------
            76864
4.) Subtrahiere die letzten drei Zahlen schriftlich von der ersten schriftlich
             8658
-             706
-           11266
-           12992
-----------------
           -16306
5.) Rechne die Zahl ins zweier komplement um, mit 8 Bit - und subtrahiere diese zahl von der ersten und rechne das Ergebnis nach dezimal
62 -106 = -44
00111110 10010110 = 11010100
6.) Multipliziere die zwei Zahlen schriftlich
51870*42648 = 2212151760
7.) Dividiere die zwei Zahlen schriftlich
52887/59048 = 0
8.) Errechne x Logarithmisch mit dem Taschenrechner
44529\^x = 1647140701
Rechne die Zahl in IEEE-754 um 8356.372070
