# Lesson 6 – Writing Numbers That Satisfy A Given Parameter.

Objective:
At the end of the lesson, students should be able to write numbers that satisfy given parameters
Sometimes, you could be asked to write numbers that satisfy certain parameters or conditions.
Using Digits To Make Numbers

Example 1
Write any three numbers you can make using all the following digits.
i) 9, 3, 7, 8, 2
ii) 3 , 0 , 6, 5, 1
iii) 4 , 2 , 1 , 8, 0

NOTE: these are open ended questions with several correct answers.
Solution: THESE ARE ONLY A FEW POSSIBLE SOLUTIONS.
i) Using the digits 9, 3, 7, 8, 2, you can make      (a) 97,328    (b) 23,987    (c) 78,329.
ii) Using the digits 3 , 0 , 6, 5, 1, you can make    (a) 10,653    (b) 65,310     (c) 51,603.
iii) Using the digits 4 , 2 , 1 , 8, 0, you can make   (a)18,024    (b) 42,180   (c) 81,204.
a) Write the largest possible number using all the following digits. b) Write the smallest possible number using all the following digits. NOTE: If 0 is one of the digits, when writing the smallest possible number, since you cannot start a number with 0, you write the second smallest digit first and 0 becomes the second digit as in the example above.
