We also have the rule that 10 x + y is divisible iff x + 4 y is divisible by 13. For example, to test the divisibility of 1761 by 13 we can reduce this to the divisibility of 461 by the first rule. Using the second rule, this reduces to the divisibility of 50, and doing that again yields 5. So, 1761 is not divisible by 13.
Two properties of 1001 are the basis of a divisibility test for 7, 11 and 13. The method is along the same lines as the divisibility rule for 11 using the property 10 ≡ -1 (mod 11). The two properties of 1001 are 1001 = 7 × 11 × 13 in prime factors 10 3 ≡ -1 (mod 1001) The method simultaneously tests for divisibility by any of the factors ...
McDonnell Douglas Corp. v. Green, 411 U.S. 792 (1973), is a US employment law case by the United States Supreme Court regarding the burdens and nature of proof in proving a Title VII case and the order in which plaintiffs and defendants present proof. It was the seminal case in the McDonnell Douglas burden-shifting framework.
The following laws can be verified using the properties of divisibility. They are a special case of rules in modular arithmetic, and are commonly used to check if an equality is likely to be correct by testing the parity of each side. As with ordinary arithmetic, multiplication and addition are commutative and associative in modulo 2 arithmetic ...
Proof by exhaustion, also known as proof by cases, proof by case analysis, complete induction or the brute force method, is a method of mathematical proof in which the statement to be proved is split into a finite number of cases or sets of equivalent cases, and where each type of case is checked to see if the proposition in question holds.

Add the rule for the divisibility rule for 7. the difference between twice the unit digit of the given number and the remaining part of the given number should be a multiple of 7 or it should be equal to 0. Example: 798 (8x2=16) 79-16=63 63/7=9 ️ 2001:4456:C7E:1400:2405:E396:8C79:2D65 10:13, 2 September 2024 (UTC)
The verification covers code, design, and implementation, and the main theorem states that the C code correctly implements the formal specification of the kernel. The proof uncovered 144 bugs in an early version of the C code of the seL4 kernel, and about 150 issues in each of design and specification.
In contract law, a severable contract (or "divisible contract") is a contract that is composed of several separate contracts concluded between the same parties, such that failing one part of such a 'severable' contract does not breach the whole contract.
