** Tarski's theorem: For every infinite set A, there is a bijective map between the sets A and A × A.

** The Cartesian product of any family of nonempty sets is nonempty.

** König's theorem: Colloquially, the sum of a sequence of cardinals is strictly less than the product of a sequence of larger cardinals.

** Hausdorff maximal principle: In any partially ordered set, every totally ordered subset is contained in a maximal totally ordered subset.

** For every non-empty set S there is a binary operation defined on S that makes it a group.

** Tychonoff's theorem stating that every product of compact topological spaces is compact.

** In the product topology, the closure of a product of subsets is equal to the product of the closures.

** If S is a set of sentences of first-order logic and B is a consistent subset of S, then B is included in a set that is maximal among consistent subsets of S. The special case where S is the set of all first-order sentences in a given signature is weaker, equivalent to the Boolean prime ideal theorem ; see the section " Weaker forms " below.

** Any union of countably many countable sets is itself countable.

** If the set A is infinite, then there exists an injection from the natural numbers N to A ( see Dedekind infinite ).

** Every infinite game in which is a Borel subset of Baire space is determined.

** The Vitali theorem on the existence of non-measurable sets which states that there is a subset of the real numbers that is not Lebesgue measurable.

** The Lebesgue measure of a countable disjoint union of measurable sets is equal to the sum of the measures of the individual sets.

** The Nielsen – Schreier theorem, that every subgroup of a free group is free.

** Cylinder head studs used in all earlier engines replaces with bolts making it easier to remove heads while engine is in engine bay.

** Some more exotic fixed-axle yo-yos have axles made from low-friction materials such as ceramic alloys — this allows for easier " sleeping ," which is essential for string tricks.

** Literally: Giving birth to a baby is easier than worrying about it.

** Programming, and training programmers, may be easier.

** It is easier to predict the exact timing of a given sequence of instructions.

** Logarithmic step size control for easier bit rate management by encoders and simplified inverse-quantization scaling

** Older Siebe Gorman-type rebreathers ( see Siebe Gorman CDBA ) had one breathing tube, which was in front of the chest and easier for the frogman to keep track of.

** use a familiar framework, making it easier to absorb.

** Relaxation technique ( mathematics ), a technique for transforming hard constraints into easier ones

** Various network address translation ( NAT ) interfaces that make it easier for players behind routers to host games.

** Various voice communication interfaces known as DirectPlay Voice that make it easier to support audio communication and voice input in games.

** Moving company, a business that puts goods into boxes to protect them and to make them easier to carry while in transit

** Native sea: Most adventures had one specific sea in which it was much easier to complete them.

** Nordic trail ratings: 3 easier, 1 more difficult, 1 most difficult

** Terrain park ratings: The Crazy Kat ( easier ), Coyote ( Intermediate ), and Apex ( Advanced ) parks.

** Active areas on screen can be highlighted using keyboard shortcuts, making them easier to find for people with visual disabilities.

** Failure to communicate objectives

** Renowned medium, Derek Acorah visited Manning's home, stating that he was able to communicate with the spirit, and that it was called " Jim " and had died from a heart attack at the age of 58 around 1900.

** Token ring, a local area network technology in which a virtual object known as a token is passed between devices on the network, authorizing them to communicate

** To let frogmen communicate underwater.

** Active communication mode: Both initiator and target device communicate by alternately generating their own fields.

** Tap codes-made by knocking on the walls, are used occasionally to communicate with divers trapped in a sealed bell or the occupants of a submersible during a rescue.

** When strangers communicate with hosts, they experience uncertainty and anxiety.

** MC6850P ACIA " Asynchronous Common Interface Adapter " — Enabled the ST to directly communicate with MIDI devices and keyboard ( 2 chips used ).

** Lack of ability of patient to communicate medication needs to others, leading to absence of doses
