Basic Concepts Shape Numbers
Depending on which circle(s) is/are colored, the same figure can represent
different numbers, as shown below. Using the numbers in the circles shown
in the box, each figure below represents the sum of the numbers in the
colored circles.
1 2
16
84 3 7 9 20
(1+2) (1+2+4) (1+8) (4+16)
Example If numbers are represented in the form of colored boxes as shown
below, what is the sum in the figure form?
1 2 5 10 19
Class Notes
The number that each box represents is 2 1.
8 2 1 represents
If 16 1 represents , and ,
the sum will be .
If you express the sum of the two numbers as the sum of the numbers that the boxes
represent, you will have + + , which can be shown as .
