 WHOLE NUMBERS

LESSON 1

FORMATION OF NUMERALS

• A number is an idea of quality e.g, how much, how many or how far.
• Numeral is a symbol used to represent a number.
• Numeration is a way of representing numbers.

16 is formed by combining 1 and 6.

327 is formed by combining 3, 2 and 7

Examples

1. Form any four numerals using all the digits 7, 6 and 9

1^st 769

2^nd 679

3^rd 976

4^th 796

2. Write the smallest numeral formed from the digits 3, 4, and 7

Digits in ascending order 3, 4, 7

Therefore; the smallest numeral = 347

3. Write the biggest numeral formed from the digits 9, 6, and 8.

Digits in descending order 9, 8, 6

Therefore; the biggest numeral 986

4. Find the sum of the biggest and the smallest numerals formed using all the digits 2, 9 and 1.

Digits in ascending order = 1, 2, 9

Smallest numeral = 129

Digits in descending order  = 9, 2, 1

Biggest numeral formed = 921

Sum  =  1 2 9

+  9 2 1

1050

5. What is the difference between the smallest and the largest numerals got from the digits 6, 2, and 5?

Digits in ascending order  = 2, 3, 6

Smallest numeral  = 256

Digits in descending order = 6, 5, 2

Difference  =  6 5 2

– 2 5 6

3 9 6
