<span>What word comes to mind when you hear “associative?” It comes from “to associate, to be grouped together.” Parentheses show the association and the operations in the parentheses are performed first. Notice that the order of the numbers does not change – only the grouping. The associative property becomes important because it allows the mathematician, you, to add or multiply numbers with ease. When you follow the examples below it will become clear how the associative property is used. The associative property can only be used for addition and multiplication, not for subtraction or division.</span>

Use the pythagorean theorem.
The foot of the ladder is 4 feet away from the building (leg 1)
The height of the building is leg 2
The ladder, which would be at an angle, is 12 feet. So our hypotenuse would be 12. The equation for this would be a²+4²=12²
We can then begin to solve
a² + 16 = 144
a² = 128
a=11.31
So, our answer is: The top of the ladder reaches the building at 11.31 feet up
10.99x4=43.96 x .05 for sales tax = 45.94 20/100= x/45.94= 100x 918.8/100 = 9.188 45.94- 9.188 =$36.752
