In base 11 vs In base 10
10 = 11
20 = 22
30 = 33
So, it is simply dividing whatever value in base 11 by 10 then multiplying it back by 11, but digit by digit.
Example, 45 in base 11:
45 = 40 + 5 (still true)
= 40/10*11 + 5 (leave the 5 untouched)
= 44 + 5
= 49 (in base 10)
The alphabets stand for numbers in different bases. For example, 10 in base 12 would be A, 11 in base 12 would be B, and 12 in base 12 would be 10, and so on. 0D=D which is 13 in base 10, and 1D can be in many different bases.
0, 1, 2, 3, 10, 11, 12, 13, 20, 21.
10 ÷ 11 ÷ 12 = (10 ÷ 11) ÷ 12 = 5/66 = 0.07575... ≈ 0.076
The numbers are -12, -11, -10 and -9.
12/11 = 108/99 10/9 = 110/99 10/9 - 12/11 = 2/99 12/11 - 10/9 = -2/99
ABC16 converted to base 10 = 10*162 + 11*16 + 12 = 2560 + 176 + 12 = 2748

bbb In numbering systems greater than decimal (base 10), we use the lowercase letters of the alphabet, in order, to delineate values greater than 9 in a single place. Thus an "a" means that there are 10 of that place value, a "b" means 11, etc. This is the equivalent of 11 * (12^2) + 11 * (12^1) + 11 * (12^0) = (11)(144) + (11)(12) + (11) (1) = 1584 + 132 + 11 = 1727 (base 10)
01 02 03 04 05 06 07 10 (= 8 in base 10) 11 (= 9 in base 10) 12 (= 10 in base 10)
It means convert the value of 12 from a number system based on 10 (our usual counting system) to a number system based on 5. In base 5 you would count to 12 this way: 1 2 3 4 10 11 12 13 14 20 21 22 Perhaps you have been learning a conversion formula. That should give you the same answer.
To subtract 11 in base 2 from 100 in base 2, you first convert both numbers to decimal. 100 in base 2 is equal to 4 in decimal (12^2 + 02^1 + 02^0). Similarly, 11 in base 2 is equal to 3 in decimal (12^1 + 12^0). Subtracting 3 from 4 in decimal gives you 1 in decimal, which is equal to 1 in binary (12^0). Therefore, 100 in base 2 minus 11 in base 2 equals 1 in base 2.
