WebMar 4, 2024 · The divisibility rule for 3 is that the sum of digits of the dividend must be divisible by 3. Notice that 2 + 6 + 1 = 9 and 9 is divisible by 3. Then 261 is also divisible by 3. The... WebDefinition If a and b are integers with a 6= 0, then adividesb if there exists an integer c such that b = ac. When a divides b we write ajb. We say that a is afactorordivisorof b and b is amultipleof a. If ajb then b=a is an integer (namely the c above). If a does not divide b, we write a 6jb. Theorem Let a;b;c be integers, where a 6= 0.
WebFeb 6, 2024 · A valid argument does not always mean you have a true conclusion; rather, the conclusion of a valid argument must be true if all the premises are true. We will also look at common valid arguments, known as Rules of Inference as well as common invalid arguments, known as Fallacies. WebClosed 7 years ago. I was asked to proof the right and left cancellation laws for groups, i.e. If $a,b,c \in G$ where $G$ is a group, show that $ba = ca \implies b=c $ and $ab = ac \implies b = c$ For the first part, I went about saying $$ba = ca \iff a = b^ {-1}ca \iff b^ {-1}c = e \iff (b^ {-1})^ {-1} = c \iff b = c$$

Discrete 2 was harder imo, but at the same time parts of it were easier. In my discrete 1 class, idk I just felt like the material had more trickery associated with it.
