Expressões numéricas com números inteiros | Aula 12

In this video, we explain how to solve numerical expressions with integers, analyzing the order of operations and the application of the rules of signs in calculations involving parentheses and multiplications. The theory arises from practice: we solve two complete numerical expressions, building step by step the reasoning necessary to correctly interpret the signs, respect the order of operations, and simplify each expression until we obtain the final result. The video "Numerical Expressions with Integers" is part of the Integers playlist, dedicated to the study of positive and negative numbers and their operations, focusing on conceptual understanding, rigor, and clarity. 🔗 Integers Playlist:    • Números Inteiros   Chapters: 00:00 - Example [12−(−4)⋅2]+5 02:15 - Example (-1)[8+(−3)⋅(5-2)] If this video helped, please consider leaving a like.
