An opened upward judgement tin dismiss live on converted into a controversy if the variable of the judgement is substituted past times a for sure constant.
For example:
Open sentence: x + four = iii for x ∈ R
If x = -1, in addition to then the higher upward judgement becomes a truthful value statement.
If x = 2, in addition to then the opened upward judgement becomes a controversy of imitation value.
Another agency to plow an opened upward judgement into a controversy is to purpose a Quantification
There are ii types of quantification inward mathematical logic, such as:
This controversy is imitation fifty-fifty if it applies to x = - 1 or x = 1 ie 12 = 1 in addition to (1)2 = 1 precisely does non apply to all x (eg x = 3, in addition to then 32 ≠ 1)
The controversy is imitation because it tin dismiss non live on determined x the master copy release < 1.

Another agency to plow an opened upward judgement into a controversy is to purpose a Quantification
There are ii types of quantification inward mathematical logic, such as:
- Universal Quantification
- Existential Quantification
1. Universal Quantification
Universal Quantification is written amongst the symbol "∀" in addition to read "for all" or "for each". If p(x) is an opened upward judgement in addition to given a universal quantification it volition live on a revelation in addition to written (∀x) p(x) read:- For each cost x apply the nature p.
- For all prices x has properties p.
Example of Universal Quantification
∀x existent number, x2 = 1This controversy is imitation fifty-fifty if it applies to x = - 1 or x = 1 ie 12 = 1 in addition to (1)2 = 1 precisely does non apply to all x (eg x = 3, in addition to then 32 ≠ 1)
2. Existential Quantification
Existential Quantification is written amongst the symbol "∃" in addition to read "any / some" or "at to the lowest degree one". If p (x) is an opened upward judgement in addition to given an existential interrogation it volition live on a controversy in addition to written (∃x) p(x) read:- there is x such that the applied properties p.
- some x convey properties p.
- at to the lowest degree i x past times nature p.
Example of Existential Quantification
∃x existent number, x < 1The controversy is imitation because it tin dismiss non live on determined x the master copy release < 1.
