Numbers in Different Bases
Besides our decimal (base 10, digits = 0-9) number system, you can work
with a binary system (base 2, digits = 0,1), an octal system (base 8, digits
= 0-7), or a hexadecimal system (base 16, digits=0-9,A-F), among others.
The same way that the decimal integer 321 means 3x10
2
+2x10
1
+1x10
0
,
the number 100110, in binary notation, means
1x2
5
+ 0x2
4
+ 0x2
3
+ 1x2
2
+ 1x2
1
+ 0x2
0
= 32+0+0+4+2+0 = 38.
