## What is associative property of equality?

The Associative Property is simply a mathematical way of stating that if we are adding three numbers, the order in which we add them does not matter. Similarly, if we are multiplying three numbers together, the order in which we multiply them does not matter. EXAMPLE 1. (3+4)+6=3+(4+6) (7)+6=3+(10)

**Why are properties of equality important?**

As equations get more complex it is important to use properties of equality to isolate the variable and solve the equation. It states that you can divide both sides of an equation by the same quantity (as long as that quantity is not equal to zero) without changing the equality.

### What are the algebraic properties of equality?

Algebraic Properties of Equality

Property | Definition |
---|---|

Reflexive | For all a, a=a |

Symmetric | If a = b, then b = a |

Transitive | If a = b & b = c, then a = c |

Substitution | If a = b, then one can replace a with b. |

**Who are the van der Bijl and another V Featherbrooke estate home?**

The first and second plaintiffs, Mr and Mrs van der Bijl (“the van der Bijls”), bring an action against the Featherbrooke Estate Home Owners’ Association (NPC) (“the Association“) and Fidelity Security Services (Pty) Ltd (“Fidelity”). 2.

## What was the cause of action for Van der Bijl?

As a result, the residence of the van der Bijls was invaded, Mr and Mrs van der Bijl were attacked by robbers and they suffered the injuries to which I have referred. They claim damages resulting from their injuries from the Association and Fidelity. 4. Mr and Mrs van der Bijl frame their cause of action as one of delictual liability.

**How are the three properties of equality related?**

A number equals itself. These three properties define an equivalence relation. For all real numbers x and y , if x = y , then y = x . Order of equality does not matter. For all real numbers x , y , and z , if x = y and y = z , then x = z . Two numbers equal to the same number are equal to each other.

### Where did Hendrik van der Bijl do his research?

He spent one semester at Halle and then moved to Leipzig University where he was supervised by Wiener, des Coudres and Jaffé. He studied ions produced by a strong Radium source moving through a dielectric liquid, the results of which verified the equation: and its description of the behaviour of such ions.
