The document discusses computer arithmetic and number representation systems including binary, decimal, octal, and hexadecimal. It provides examples of converting between these different number systems, such as converting 1011001012 to its decimal value of 35710. Conversion methods covered include dividing numbers into place values to determine the decimal equivalent. References are also listed for additional reading on computer organization and architecture.

4. Binary to Decimal Conversion(vice versa)
Example
1011001012 = 35710

5. Octal to Decimal Conversion(vice versa)
Example
52910 = 10218

6. Hexadecimal to Decimal Conversion(vice versa)
19889(10) = … (16)
19889/16 = 1243 sisa 1
1243/16 = 77 sisa 11 (B)
77/16 = 4 sisa 13 (D)
Hasil Konversi : 4DB1
Example
48 (16) = . . . (10)
= (4 x 161) + (8 x 160)
= 64 + 8
= 72
Hasil Konversi : 72

7. Binary to Octal (vice versa)

8. Binary to Heksadecimal (vice versa)

9. Octal to Hexadecimal (vice versa)
“Change it to binary then do the
conversion”
4458 = . . .16
