Hello, I would like to ask you if there is a mathematical theory, that is complete (in the sense of Goedel's theorem) but practically applicable. I know about Robinson arithmetic that is very limited but incomplete already. So, I would like to know if there is some mathematics that could be practically used (expressiveness) and reduced to logics (completeness).
You probably intended to restrict the question to effectively axiomatizable theories. Otherwise, for example, the first-order theory of the standard model of arithmetic is a complete theory, as is the theory of the standard model of ZFC.
Gödel's incompleteness theorem establishes some limitations on which effective theories can be complete. It shows that no effective, complete, consistent theory can interpret even weak theories of arithmetic such as Robinson arithmetic. However, there are many mathematically interesting theories that do not interpret the natural numbers.
Perhaps it is worth adding some comments to the list of non-trivialcomplete theories given by Carl Mummert. One remark is that thecompleteneness of Euclidean geometry is a consequence of that of thereal closed ordered fields (exploiting the possibility to"arithmetize" geometry using cartesian coordinates). The other isthat the completeness of the theory of dense linear orderings withoutendpoints is only one in a set consisting of related theories.Actually, all the 4 possible theories of dense linear orderings, thatis, those without endpoints, having both first and last elements,having only first, and having only last element arecomplete. Analogously all the 4 possible theories of discrete linearorderings (with the additional requirement of infiniteness in the caseof having both first and last elements) are also complete. Moreover,there is a nice analogy between linear orderings and Boolen algebras(BA's) in this respect: atomless BA's correspond to dense orderings,atomic BA's to discrete orderings. Indeed, both the theory of atomlessBA's and the infinite atomic ones are complete.
This answer is possibly unhelpful and definitely under-informed, but a good source to look into might be the book Complete Theories by Abraham Robinson. I haven't read it, I just happened to see it as I was perusing the mathematics section in my library. If you have done any research, you may have come across this book. If not, it would be worth checking out.
Not exactly complete in the sense of Goedel, but more in the sense of Garrett Birkhoff (yes, I am talking about equational logic, where the theories considered are often, but not always, universally quantified equations such as associativity and distributivity).Term rewriting systems occur in computer science and occasionally work with complete equational theories. While not as expressive as logics with relation predicates other than equality, equational theories are complete in equational logic, sometimes are recursive, sometimes have a finite set of equations which (along with the rules for equational logic) generate all the other equations belonging to a theory, and have nice classes of models (cf Birkhoff's HSP Theorem).
I am looking for a complete book or website of mathematics, which has everything about Mathematics like Riemann geometry ,calculus, complex analysis,lie theory,calculus of variations etc(many others).
ALEKS is a mathematics assessment and preparation tool. The assessment is designed to identify the best mathematics course for you to start in, given the mathematics requirements of your major. The ALEKS PPL consists of:
The assessment consists of approximately 30 questions, designed to pinpoint for Towson University where you should start your mathematics pathway, depending on the mathematics requirements of your major. On average, it takes approximately 90 minutes to complete, and you have a 4-hour window to complete it.
Note: In general, an improved score from an unproctored ALEKS assessment can only be used to place in one course higher than the original placement and may require special department approval. Additionally, if any unproctored ALEKS placement score is inconsistent with your mathematics record known to TU, the Math Department reserves the right to require you to retake ALEKS in a remotely proctored setting online. For a proctored assessment, contact the Mathematics Department.
If you are unhappy with your second score, you may email the mathematics department at math AT_TOWSON to make an appointment for a third attempt. You must spend at least 5 hours in the learning module between attempts. All attempts after the second will be taken in a remotely proctored environment online.
If your intended major(s) require calculus, your score will be used to help place you into the most appropriate math course during your first semester at Case Western Reserve University. If your intended major does not require calculus, you are still required to complete the math placement, but do not need to register for a calculus course in the fall.
Program Purpose: Students who complete Mathematics courses will demonstrate critical thinking skills, analyze abstract concepts, and transition from the concrete to the abstract in mathematical thinking.
The Mathematics Associate in Science Degree program offers training in both pure and applied mathematics, leading to careers in research, education, business, industry, and government, including such professions as educators, statisticians, actuaries, and operations research analysts. Many areas, such as the physical and social sciences, engineering, economic, and business, are dependent upon the use of applied mathematics in developing solutions to practical problems. Students who complete Mathematics courses will demonstrate critical thinking skills, analyze abstract concepts, and transition from the concrete to the abstract in mathematical thinking.

For summer 2023, CSUF is offering the web-based ALEKS program to students who have chosen majors requiring completion of Calculus (Math 150A Calculus I or Math 135 Business Calculus or Math 130 Calculus for the Natural Sciences). ALEKS is a research-based, on-line learning program that is free to you. ALEKS utilizes artificial intelligence to assess your Calculus readiness. It then provides you with a set of individualized online modules to complete prior to being reassessed for Calculus readiness. This process is repeated three additional times. You should expect to spend about 20 hours total to complete all four modules and assessments. Completing ALEKS will ensure you enroll in your best fit CSUF mathematics course and prepare you to succeed academically in your first term at CSUF.
Between any two ALEKS assessments, you will work through individualized ALEKS learning modules to refresh and improve your math skills. Each of the assessments has a two-hour time limit. There is a 24-hour waiting period between each assessment. Each assessment is up to 30 questions and generally takes 60-90 minutes to complete. Therefore, you may plan your time as follows:
