expressions

Expressions are combinations of symbols, words, or formulas that convey ideas, feelings, or information. In mathematics and language, an expression can be a number, a variable, or a mix of both, created using operations like addition or multiplication. For example, "3 + 5" or "x - 2." They represent values or concepts and can be simplified or expanded to better understand or solve problems. Essentially, expressions are tools to communicate complex ideas efficiently and clearly, whether in everyday language or technical fields.
