Data Types, Operators, and Expressions
2023Now that you have been familiarised with the installation and basics of Python programming, it's time to dig in a little more and understand the different data types that are available along with the operators and expressions that make the programming more user-friendly.

Expressions, Operands and Operators
2004In the previous three chapters we have examined various types of variables and now in this chapter we turn to ways of manipulating the information they hold. We shall introduce the concepts of expressions, operands and operators. Expressions are used to calculate a result involving a number of operands (either variables or constants).

Operations on certain expressions
USSR Computational Mathematics and Mathematical Physics, 1971Abstract ALGORITHMS are described for some natural transformations of rational expressions of several which are in general inhomogeneous (the coefficients are integers throughout). With the increasing interest in the transformation of expressions by computer, suitable transformation algorithms need to be developed.

Understanding Operators and Expressions
2014In this chapter we will see what operators and expressions are and the different types we can use in our Dart applications. At the end of the chapter we’ll review how to create your own operators.

Types, Operators and Expressions
1995A data object holds a value of specific type. VHDL provides three classes of objects: variables, signals and constants. Declarations list the data objects to be used, state what type they are, and perhaps what their initial values are. An expression is a formula that defines the computation on the data objects. Expressions perform arithmetic or logical

Chapter 1 demonstrated how to use statements to get the computer to do something. The statements were made up of keywords and symbols that end with a semicolon. The next step is to examine expressions.

ACM SIGPLAN Notices, 1973
Conventional languages are serial from statement to statement unless broken by explicit parenthesization such as BEGIN blocks or their equivalent in other languages. However, they are not serial within statements, but possess a complex priority scheme which seems to have little justification except historical notation in a few branches of mathematics ...

Operators, Expressions, and Program Flow
2010The focus of this chapter is an in-depth look at each of the ways that we can evaluate code, and write meaningful blocks of conditional logic. We’ll cover the details of many operators that can be used in Python expressions. This chapter will also cover some topics that have already been discussed in more meaningful detail such as the looping ...

Expressions: Operations on Data
2019We already used expressions a couple of times. Whenever you need to assign a value to a variable, need function call parameters, or need to provide a value to some kind of language construct, you need an expression. Expressions also show up where you don’t expect them, and they can be ignored if we don’t need them.
