Directions
In this chapter, we will learn how to use reasoning to think clearly and solve
problems. We will also explore how analysis helps us understand things better by
breaking them down into smaller parts.
NUMBER PYRAMID
In number pyramid, the number in each space is the sum of the two numbers
below it.
Start with a circle, which has two filled adjoining circles below it.
Blue circle will be the sum of two green circles.
9
5 4
3 2 2
2 1 1 1 2 1 1 1
Therefore, blue circle will be 2 + 1 = 3.
We will get the remaining numbers by following the same pattern.
What if you could use computer to create secret codes that only your
friends could decode? What would your code say, and how would you
use it to communicate?
