That is part of a psychology knownas "gestalt psychology", first promoted around 1900 by Christian von Ehrenfels. Its premise is that "the whole is greater than the sum of its parts"
First, work out the sum of all numbers and divide by three. 1+2+3+4+5+6+7+8+9+10+11+12=78. 78/3=26. This means each part needs to equal 26. To get equal parts you need to divide the clock into thirds. 11+12+1+2=26, 5+6+7+8=26, leaving 10+9+3+4=26 in the middle.
The exterior angles of polygons equal 360 degrees.
The sum of all of the angles in a trapezoid is 360 degrees. The sum of interior angles for an n-sided polygon is equal to 180(n-2) which, in this case, is 180(4-2) = 360.
the sum of the angles of a trapizoid equal 360 degrees.
The sum of all 30 interior angles would equal 5040*.
If you mean the numbers are all 15 then the answer is 45 otherwise the answer is the 15 that you already stated in your question to be the sum.
they are equal.
the volume of its parts would be equal to the amount off butts an object gives off
This will happen if the fractional parts of the numbers sum to 1.
synergy
It is a saying to describe synergy. Mathematically, though, the whole is equal to the sum of the parts - not more nor less.
The whole is equal to more than the sum of its parts is a quote from Aristotle. Another quote from Aristotle is the body is most fully developed [at] from thirty to thirty-five years of age, the mind at about forty-nine.
The sum of all the power drops in a series circuit must equal
The sum should equal to 1.
The sum of all four angles would equal 360º.
The sum of all (interior) angles must equal 360 degrees
By definition, the sum must be unity.
