The file with the suffix tnd is the formula of communication letter. A file with the suffix daf is a trader's formula. To import these two formulas, you need to install two kinds of stock software, namely, Tongda letter and trader.

1. Tongda letter stock trading software is a mobile securities software designed by Shenzhen Fortune Trend Micro Co., Ltd., which is positioned as a securities information platform providing multi-functional services.

Third, the formula, in mathematics, physics, chemistry, biology and other natural sciences, uses mathematical symbols to express the relationship between several quantities. It is universal and applicable to all similar problems. In mathematical logic, a formula is a formal grammatical object to express a proposition, but the proposition may depend on the free variable value of the formula. The precise definition of a formula depends on the specific formal logic involved, but there is a very typical definition (for first-order logic): the formula is defined relative to a specific language; That is, a set of constant symbols, function symbols and relational symbols, in which each function and relational symbol has an independent variable to indicate the number of parameters it accepts.

Fourthly, according to the semantic inference rules of predicate logic, semantics should be consistent, that is, for a set of propositional logic statements F, if and only if there is at least an explanation that all elements of F are true under I, then F is semantically consistent. In propositional logic semantics, an assignment cannot give a propositional atomic formula both truth and false. In propositional logic semantics, under the same interpretation, a set cannot belong to both the extension of a predicate and the extension of this predicate.

5. If the user can't find the formula in the built-in formula provided by Word20 10, he can point to the "Other formulas in Office" option in the formula list and select the required formula from the list of more formulas opened on the Office website.
