Problem 3[edit]

Everybody is born to biological parents. Our parents each had biological parents. We can say that our grandparents are mathematically as the number of our ancestors doubles with each generation we go back.
So:
3.a How many times would 2 be multiplied to determine the number of great grandparents?
3.b How many times would 2 be multiplied to determine the number of great-great grandparents?

Problem 4[edit]

Example[edit]

We can identify the square numbers between two numbers by simply squaring basic numbers. For example:
To identify the square numbers between 20 and 40 we can say
is too small
is in the range
is in the range
is too large
So the square numbers in that range are 5 and 6.

Problems[edit]

4.a Identify the square numbers between 50 and 100
4.b Identify the square numbers between 160 and 200.
