In base ten, consecutive places differ by factors of ten.
In base ten, ten is not a prime number. It is divisible by both 2 and 5. In base 2, however, 10 is equal to two in base ten and two is a prime number.

The binary representation of the decimal number 77 is 1001101.
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.
The base of a number is the size of the groups in a counting system. The system we use is base 10. The smallest two-digit number, 10, represents a group of ten units or 101. 100 is ten groups of ten units or 102. 1000 is ten groups of ten groups of ten units or 103, and so on. The base is also the number of different digits used in the counting system including 0. Computer designers and low level programmers are also familiar with base 2 (binary), base 8 (octal) and base 16 (hexadecimal). In binary, 10 represents a set of two units or 21, 100 is two sets of two or 22, 1000 is two sets of two sets of two or 23, and so on. When a base other than 10 is being used, the base is often written as a subscript after the number. For example, 101012 = 258 = 2110.

In usual mathematics (base ten, normal addition), 2 + 2 = 4.
Binary is base 2, decimal is base 10. Base 10 positions from the decimal point are tens, hundreds, thousands, etc etc. - each one ten times the previous. Base 2 positions from the decimal point are twos, fours, eights, sixteens etc etc - each one is two times the previous. In base ten there are 9 digits plus zero In base two there is one digit (1) and zero. Sixteen in base ten is 16, in base two it is 10000. Eighteen is 18 and 10010 respectively.
