A binary operation on a set R is called associative if it satisfies the associative law: \((x \times y)\times z=x \times (y \times z)\) for all \(\displaystyle{x},{y},{z}∈{R}\)
We know that the usual operator addition \((+)\), subtraction \((-)\) and multiplication \((\times)\) all are binary operator and all these operator satisfies the associative property.
In order words, if you are adding or multiplying it goes not matter where you put the parenthesis.
Thus using the associative property we get \((-6+3)+1=-6+(3+1)\)

Write a short paragraph explaining this statement. Use the following example and your answers How long does it take the particle to go once around the circle? Find parametric equations if the particle moves twice as fast around the circle. The position of a particle is given by the parametric equations \(x = \sin t, y = \cos t\) where 1 represents time. We know that the shape of the path of the particle is a circle.

Write a short paragraph explaining this statement. Use the following example and your answers Does the particle travel clockwise or anticlockwise around the circle? Find parametric equations if the particles moves in the opposite direction around the circle. The position of a particle is given by the parametric equations \(x = \sin t, y = \cos t\) where 1 represents time. We know that the shape of the path of the particle is a circle.
