Each place value column in base 2 is twice that of the column to its right.
→ 11₂ = 1 × 2 + 1 = 3 in base 10.
It is 3.
101 in base 2 is 5 in decimal. 11 in base 2 is 3 in decimal. 5 - 3 is 2 in decimal. 2 is 10 in base 2.

2 plus 2 can equal 11 when you are counting in base 3. However, as it is not expressed in a decimal base, this answer would not be read "eleven" but "one one".
Your question, "Is there any way 2 plus 2 can equal anything but 4?" My answeris YES. If you were to use base 3 math, 2 plus 2 would then equal "11" (base 3) 2 plus 2 = 11 (base 3)
given 1111 that would be in base10 20+ 21 + 22 + 23 = 1 + 2 + 4 + 8 = 15 you count using 2x and read right to left given 1011 20 + 21 + 23 = 1 + 2 + 8 = 11
.11 base 10 is approx (0.00011100001) base 2
Using base10 number system, it is: 2000 +0002 ----- 2002
101 in base 2 is 5 in decimal. 11 in base 2 is 3 in decimal. 5 - 3 is 2 in decimal. 2 is 10 in base 2.
1B base 16 = 27 base10
Convert each value to base10 & then sum In base4 the places are 1, 4, 16, 64 So 3210 base4 = 3*64 + 2*16 + 1*4 = 228 In base 3 the places are 1, 3, 9,27 So 210 base 3 is 2*9 + 1*3 = 21 In base 2 the places are 1,2,4,8 So 10 base 2 = 1 * 2 = 2 So 228 + 21 + 2 = 251

In which language?
11 = 1*8 + 1*2 + 1*1 = 1(2)3 + 1(2)1+ 1(2)0. Thus, in binary (base 2) 11 is represented as: 1011. To double check we get: 8 + 2 + 1 = 11 (base 10).
All of them (as well as other bases) are based on the place-value system: in decimal, each digit has a place-value that is 10 times as much as the digit to the right. In base 2, and base 16, the factors 2 and 16, respectively, are used instead. Base 2 needs 2 different symbols (0 and 1) to represent each digit; base 10 needs 10 symbols (0-9), and base 16 needs 16 different symbols. For this purpose, apart from the digits 0-9, the letters A-F are also used as "digits", where A means 10, B means 11, etc.
. All number systems have the same three characteristics: Digits, Base, Weight. the decimal system has the following characteristics:Ten Digits 0, 1, 2, 3, 4, 5, 6, 7, 8, 9; has base10 and whight powers of base 10 ( 10,.100,1000 , ........and so on )by mohsh20@gmail.com
