What is the associative property?
You probably have different groups of friends and you hang out with them at different times. The associative property deals with changing groups (parentheses). You don’t change the order, you just change the groups.
When do you use the distributive property?
The distributive property applies when you are multiplying a number (or variable) times a quantity. You can multiply the number by each of the values inside the quantity seperately, and add them together. Take a look at the distributive property below: The word distribute means to give out.
What does "commute" mean?
The word commute means to travel: “A half hour commute to work.”. When you see the word commutative, think of travel – or of moving the order of the numbers. Tip to remember: Commutative also sounds like com-move-ative. Distributive Property.
When is the distributive property most useful?
The distributive property will be most useful when one of the numbers inside the parentheses is a variable. Certain math properties are only useful in some situations. Identify Property. he word identity means “who you are.”. You may have heard of identity theft.
What is the identity operator of addition?
he identity operator of addition is 0 because any number plus 0 is always equal to that number – and yes, you can switch the order! The identity operator of multiplication is 1 because any number times 1 is always equal to that number – again you can use the commutative prop!
What is the associative property?
This property states that when three or more numbers are added (or multiplied), the sum (or product) is the same regardless of the grouping of the addends (or multiplicands). For example:
What is the identity property of a number?
Identity Property: Additive identity. Multiplicative identity. Additive identity is a number, which when added to any number, gives the sum as the number itself. This means, the additive identity is “0” as adding 0 to any number, gives the sum as the number itself.
What is the multiplicative identity of a number?
Multiplicative identity is a number, which when multiplied by any number, gives the product as the number itself. This means, the multiplicative identity is “1” as multiplying any number by 1, gives the product as the number itself.
Purplemath
There are three basic properties of numbers, and your textbook will probably have just a little section on these properties, somewhere near the beginning of the course, and then you'll probably never see them again (until the beginning of the next course).
MathHelp.com
Why not? Because every math system you've ever worked with has obeyed these properties! You have never dealt with a system where a×b did not in fact equal b×a, for instance, or where (a×b)×c did not equal a× (b×c). Which is why the properties probably seem somewhat pointless to you.
Distributive Property
The Distributive Property is easy to remember, if you recall that "multiplication distributes over addition". Formally, they write this property as " a(b + c) = ab + ac ". In numbers, this means, for example, that 2 (3 + 4) = 2×3 + 2×4.
Associative Property
The word "associative" comes from "associate" or "group"; the Associative Property is the rule that refers to grouping. For addition, the rule is " a + (b + c) = (a + b) + c "; in numbers, this means 2 + (3 + 4) = (2 + 3) + 4. For multiplication, the rule is " a(bc) = (ab)c "; in numbers, this means 2 (3×4) = (2×3)4.
Commutative Property
The word "commutative" comes from "commute" or "move around", so the Commutative Property is the one that refers to moving stuff around. For addition, the rule is " a + b = b + a "; in numbers, this means 2 + 3 = 3 + 2. For multiplication, the rule is " ab = ba "; in numbers, this means 2×3 = 3×2.
Worked examples
I'm going to do the exact same algebra I've always done, but now I have to give the name of the property that says its okay for me to take each step. The answer looks like this:
What is the third side length of a triangle?
From the question, it is given that two sides of triangle are 12 cm and 15 cm. So, the third side length should be less than the sum of other two sides, 12 + 15 = 27 cm. Then, it is given that the third side is cannot not be less than the difference of the two sides, 15 – 12 = 3 cm.
What is the hypotenuse of a right angled triangle?
By the rule of Pythagoras Theorem, Pythagoras theorem states that for any right angled triangle, the area of the square on the hypotenuse is equal to the sum of the areas of square on the legs. In the above figure RQ is the hypotenuse, 15 2 = 12 2 + a 2.

What is a triangle with two equal sides called?
A triangle having two equal sides is called an isosceles triangle. A triangle having three equal sides is called an equilateral triangle. Classification of triangles based on angles. If each angle is less than 90°, then the triangle is called an acute-angled triangle.
How many medians does a triangle have?
Since there are three vertices in a triangle, therefore, a triangle has three medians. Altitudes of a Triangle. A line segment drawn from a vertex of a triangle perpendicular to its opposite side is called an altitude (height) of the triangle corresponding to the opposite side.
What is the measure of an exterior angle of a triangle?
The measure of an exterior angle of a triangle is equal to the sum of the measures of its two interior opposite angles. Angle Sum Property of a Triangle. The sum of the measures of the three angles of a triangle is 180°. Two Special Triangles: Equilateral and Isosceles.
What is an equilateral triangle?
Equilateral Triangle: A triangle in which all three sides are of equal length is called an equilateral triangle. In an equilateral triangle. (i) all sides have the same length and. (ii) each angle has measure 60°. Isosceles Triangle: A triangle in which two sides are of equal length is called an isosceles triangle.
What is an isosceles triangle?
Isosceles Triangle: A triangle in which two sides are of equal length is called an isosceles triangle. In an isosceles triangle. (i) two sides have the same length. (ii) base angles opposite to the equal sides are equal.
What is the sum of the lengths of two sides of a triangle?
Sum of the Lengths of Two Sides of a Triangle. The sum of the lengths of any two sides of a triangle is greater than the third side. Right-Angled Triangle and Pythagoras Property. A triangle whose one angle is a right-angle is called a right-angled triangle.
What is a right angled triangle?
A triangle one of whose angle measures 90° is called a right-angled triangle. A triangle one of whose angle measures more than 90° is called an obtuse angled triangle. Each angle of an equilateral triangle measures 60°. The angles opposite to equal sides of an isosceles triangle are equal.
