An unsigned integer cannot be negative. It has a maximum positive value twice that of a signed integer. Max signed: 128 Max signed: 256 I could be off by one there, though.

You multiply an integer by itself twice or multiply 1 by an integer three times.
x = 3 + 2y
??? explain better.
One (negative) is preceded by a - sign and the other (positive) is not. Negative integers have values less than zero, whereas positive integers have values greater than zero. If a positive and negative integer are made up of the same digits and in the same order (e.g., 2 and -2, or 896 and -896), then when added together they will equal zero. If, however, one is subtracted from the other, then they will equal twice the number from which the other is subtracted.

Twice a number increased by eight is greater than negative four.
