In bionary 1 and 0 are the only numerals and counting with them looks like this
0, 1, 10, 11, 100, 101, 110, 111, 1000, 1001, 1010. (zero to ten)
so the way for showing 2 is now 10. so 1+1=10 as 10+10=100 (i.e 2+2=4)
1 + 1 = 10 in binary numbers.
10
1 plus 1 = 2
0=0 in binary 1=1 2=10 3=11 . . . Got it?
In a binary system, where only the digits 0 and 1 are used, the addition of 2 (represented as 10 in binary) and 2 (also represented as 10 in binary) equals 100 in binary, which is 4 in the decimal system. Therefore, in this specific context, 2 plus 2 equals 11.
1 + 1 = 10 in binary numbers.
1 plus 1 = 2
10
2 decimal, or 10 binary.
1 plus 1 = 2
When you are working in binary arithmetic.
0=0 in binary 1=1 2=10 3=11 . . . Got it?
In a binary system, where only the digits 0 and 1 are used, the addition of 2 (represented as 10 in binary) and 2 (also represented as 10 in binary) equals 100 in binary, which is 4 in the decimal system. Therefore, in this specific context, 2 plus 2 equals 11.
1 plus negative 10 is equal to -9.
1 + 10 + 20 = 31
It is not magic. While incorrect in "base ten", the eqauation is correct in binary numbers (base two). The sum 1+1=10 because the value "10" (base two) is equal to 2 in base ten.
In binary it's the equivalent of decimal 3.
