Simple InequalityLife is full of inequalities as can be seen in this photo. In mathematics, numbers can be large or small. The expression:
puts a condition on the unknown x that x + 1 must be greater than or equal to 5. Each value of x that satisfies the condition is said to be a solution of this inequality. One solution is x = 4, another is x = 4.5, yet another x = 10. The xaxis represents all real numbers from minus infinity to infinity. As you move left on the xaxis the numbers get smaller, as you move right they get larger. To better understand inequalities and numbers on the xaxis, let's perform an experiment.
