ByNegative Binary Numbers. In decimal we are quite familiar with placing a “-” sign in front of a number to denote that it is negative The same is true for binary numbers a computer won’t understand that What happens in memory then?. Binary Negative Numbers. There are several representations

ByNumber Systems. Why binary numbers?. Digital systems process information in binary form. That is using 0s and 1s (LOW and HIGH, 0v and 5v). Digital designer should be familiar with: binary math. Conversion between binary and other number systems.
