1. In mathematics, a solution to an equation that is a real number (as opposed to a complex number with an imaginary component)
The quadratic equation x² - 4 = 0 has two real solutions: x = 2 and x = -2
A equação quadrática x² - 4 = 0 tem duas soluções reais: x = 2 e x = -2
2. In general contexts, a practical and effective solution to a problem, not theoretical or imaginary
We need a real solution to climate change, not just empty promises
Precisamos de uma solução real para as mudanças climáticas, não apenas promessas vazias
