What does ± mean?
O símbolo mais ou menos ± desempenha uma dupla função técnica em ciências exatas. Na álgebra elementar indica a coexistência de raízes positivas e negativas, como na resolução de equações do segundo grau. Na engenharia, química e controle de qualidade, define a margem de tolerância aceitável em torno de um valor medido (por exemplo, 220 ± 5 V).
Sua notação condensada poupa espaço ao unificar duas condições opostas numa única declaração matemática precisa. É muito usado ao lado do sinal de multiplicação, do símbolo de divisão e dos demais símbolos matemáticos do SymbolHub.
