A scientist, for example.
An expression.
An arithmetic operation combines two numbers while a logical operation uses two logical values which can be true or false. The arithmetic operation uses adding or subtraction to reach the correct answer.
Algebra uses variables to represent the unknown numeral.
Algebra is the branch of mathematics that uses letters called variables in place of numerals. Algebra is an extremely important foundation of every branch of mathematics.

Expression
An expression.
A mathematical phrase that uses variables, numbers, and operation symbols is called an "algebraic expression." For example, the expression (3x + 5 - 2y) includes the variable (x), the constant (5), the variable (y), and operations such as addition and subtraction. Algebraic expressions can represent a wide range of mathematical relationships and can be simplified or evaluated based on the values assigned to the variables.

An algebraic model uses variables and numbers. Example: x*54=648
Algebra uses letters to represent unknown numbers.
A mathematical system that uses variables to represent numbers is called algebra. In algebra, symbols (often letters) are used to represent unknown values or quantities, allowing for the formulation of equations and expressions. This system enables the manipulation of these symbols according to established rules, facilitating problem-solving and the exploration of relationships between variables. Algebra is fundamental in various fields, including science, engineering, and economics.
