In an equation and inequation there are always unknown numbers that we have to figure out. What we can insert for this unknown number is defined by the base quantity G. For example, G =
In the inequation, different signs appear: bigger, smaller, bigger or equal to, smaller or equal to. For more information please look for the title “Bigger or Smaller” in “Fifth grade”. To find the solution of an equation or inequation, we have to look for numbers that we can insert in the place of the variable so we become a product. Example: 5 + (3 ∙ x) = 23 L (L means solution set quantity) = {6} x – (24 : 3) > 2 L = {11, 12, 13, …} There is the possibility to change equations or inequations by simplifying them without changing the solution set quantity. This means that the solutions stays the same. That is how many equations and inequations can be calculated. These changes are called equivalence changes. There are differences between equations and inequations.
