## What is the base 9 number system?

Nonary system

In number system, base 9 number system is also called Nonary system. In this system, each digit is written as two ternary (base 3) digits. Unlike how octal (base 8) and hexadecimal (base 16) systems are used in place of binary (base 2), base 9 number system can be used to compact representation of ternary.

**How do you multiply by base 5?**

Example showing how to do multiplication in base five

- 6 × 4 = 24. 24 = 10 + 10 + 4.
- 4 × 3 = 12. 12 = 5 + 5 + 2.
- 6 × 6 = 36. 36 + 2 = 38 tens.
- 4 × 4 = 16. 16 + 2 = 18 fives.
- 6 × 8 = 48. 48 + 3 = 51 hundreds.
- 4 × 3 = 12. 12 + 3 = 15 twenty-fives.
- 3 × 4 = 12 tens. 12 tens = 10 tens + 2 tens = 100 + 2 tens.
- 2 × 3 = 6 fives.

### What two numbers make 9?

2 + 7 = 9, cross out 2 and 7. 2.4 + 3 = 9, cross out 4, 3 and 2. 3. There are no other groups of numbers adding up to 9.

**What number of cases are there in multiplication by series of 9?**

There are three cases for the multiplication of numbers with a series of 9’s. The method to solve ‘Case 1’ and ‘Case 2’ is the same, but for ‘Case 3’, the method is different.
