__Objective:__

At the end of this 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, SMALLEST AND LARGEST POSSIBLE NUMBERS____. __

__Example 1__

Write any three numbers you can make using all the following digits.

1) 9, 3, 7, 8, 2

2) 3 , 0 , 6, 5, 1

3)4 , 2 , 1 , 8, 0

**NOTE: these are open ended questions with several correct answers.**

__Solution__

1) Using the digits **9, 3, 7, 8, 2**, you can make

**(a) 97,328 (b) 23,987 (c) 78,329****.**

2) Using the digits **3, 0, 6, 5, 1,** you can make

**(a) 10,653 (b) 65,310 (c) 51,603****.**

3) Using the digits **4, 2, 1, 8, 0,** you can make

(a)**18,024, (b) 4 2,180 (c) 81,204**.

**Example 2**

Write the largest possible number using the following digits.

- 8, 6, 0 , 8 , 9 …………..
**98860** - 5, 7, 1, 1, 3 ……………..
**75311**

Write the smallest possible number using all the following digits.

- 6, 9, 0, 1, 4 ………………….
**10469** - 3, 3, 5, 1, 2 ………………..
**12335**

** NOTE**: If 0 is one of the digits it cannot be written as the first number because a number cannot begin with a 0. Since you cannot start a number with 0, you write the second smallest digit first before the 0. The zero then becomes the second digit as in the example above.
