Many students learn the order of operations using PEMDAS (Parentheses, Exponents, Multiplication, Division) as a memory aid. If we want to simplify set operations such as taking the complement, union, and intersection of sets, then we use De Morgan's laws. Whole numbers are numbers which are not FRACTIONS , DECIMALS or NEGATIVES. Let's call this force How to find the resultant force? Demorgan's laws are a set of two postulates that are widely used in set theory. Since p and q represent two different statements, they cannot be the same.
