Though such students may think that they know what they mean, this usage is not standard in mathematics and should be discontinued by students who wish to proceed in higher mathematics. Another word for “or” is disjunction; the most commonly used symbol for it is ∨. Another word for “...

The intersection AÇB is the set of all elements that belong tobothA and B. The union AÈB is the set of all elements that belong to A and/or B ("and/or" means "either or both"; it is the explicitlyinclusiveversion of the more ambiguous "or" conjunction, which normallydoesmean "...
Infinity is not a number, but theideaof numbers going on for ever. You cannot add one to infinity, anymore than you can add one to a person, or to love or hate. x¯is the mean of all the possible values of x. You will mostly come across this symbol in statistics. ...
In a nutshell, we are going to derive an information-theoretic measure able to grasp the consistency of the shared information between agents, when mean- ing is introduced as a primitive referential value attributed to one or more signals. minimizing the heat loss during the transmission process....
(logically)atomicpropositions are theorems. Now mathematical triviality implies full triviality in the presence of the rule ECQ. But in general it does not do so. Yet, it is mathematical triviality that is catastrophic for mathematics: no calculation would mean anything. And in Dunn's argument...
“I have always been good at mathematics”) with answers ranging from 1 (does not apply at all) to 4 (applies completely) on a 4-point Likert scale. A mean score was calculated from these items. Mathematical self-concept was assessed in Grade 5; Cronbach’s alpha for this scale was ....
These strings and these pictures, considered for themselves, are dead signs (to use this Wittgensteinian metaphor again), and Parsons’ ‘intuition’ can no more bring them to life than anything else can; that is: it cannot determine what they are supposed to mean. By simply looking at the...
Ainsworth (1999) proposed that MERs could be used to promote abstraction as one example of their constructing function, which can mean either subtracting a concept to its essentials, identifying underlying patterns of a concept, or creating a completely new higher-level mental entity. According to ...
Which would mean if a particular expression were to be compiled twice, each expression would have its own unique symbol_table which in turn would have its own instances of those variables. Examples of such variables could be: (1) x or y (2) customer_name The following is a diagram ...
