For example, to subtract 23 – 12 in base 4, we subtract 3 – 2 to get 1 in base 4. However, since 2 is less than 3, we borrow 1 from the next column, making it 13 in base 4. We then subtract 1 – 1 to get 0 in base 4.

Multiplying numbers in base 4 involves multiplying each digit of one number by each digit of the other number and adding the results. For example, to multiply 23 by 12 in base 4, we multiply 3 by 2 to get 10 in base 4 and 3 by 1 to get 3 in base 4. We then add 10 and 3 to get 13 in base 4, which is equivalent to 7 in base 10.

Dividing numbers in base 4 can be challenging but follows similar principles to division in base 10. We divide the dividend by the divisor and find the quotient and remainder. For example, to divide 23 by 2 in base 4, we find that 2 goes into 23 eleven times with a remainder of 1 in base 4. Therefore, the quotient is 11 and the remainder is 1 in base 4.

In conclusion, mastering arithmetic operations in base 4 is essential for understanding mathematical concepts in different number systems. By following the principles outlined in this subchapter, students can confidently add, subtract, multiply, and divide numbers in base 4 and apply their knowledge to solve complex mathematical problems.

## 8: Base 3 – Ternary System

### Introduction to Base 3 System

In mathematics, the base of a number system refers to the number of different digits or combination of digits that can be used to represent numbers. The most common base used in everyday calculations is base 10, also known as the decimal system. This system uses ten different digits, from 0 to 9, to represent all numbers. However, there are other number systems that use different bases, such as base 9, base 7, base 6, base 5, base 4, base 3, and base 2. In this subchapter, we will explore the base 3 system and how it can be used in mathematical operations.

The base 3 system, also known as the ternary system, uses three different digits – 0, 1, and 2 – to represent numbers. In this system, each digit’s value is multiplied by the base raised to the power of its position from right to left. For example, the number 102 in base 3 can be converted to base 10 by multiplying 1 by 3^2, 0 by 3^1, and 2 by 3^0, and adding the results together. This gives us 1*9 + 0*3 + 2*1 = 11 in base 10.

One of the advantages of using the base 3 system is that it can represent numbers more compactly than the decimal system. For example, the number 10 in base 10 would be represented as 101 in base 3. This can be useful in computer programming and other applications where space is limited. Additionally, working in different bases can help students develop a deeper understanding of how numbers work and improve their problem-solving skills.

To convert a number from base 10 to base 3, one can use the method of repeated division. This involves dividing the number by the base (3 in this case) and keeping track of the remainders until the quotient is 0. The remainders, read from bottom to top, give the number in base 3. For example, to convert the number 21 in base 10 to base 3, we would divide 21 by 3 to get a quotient of 7 and a remainder of 0. Dividing 7 by 3 gives a quotient of 2 and a remainder of 1. Therefore, 21 in base 10 is equivalent to 210 in base 3.

In conclusion, the base 3 system is a unique and interesting way to represent numbers in mathematics. Understanding different number systems, such as base 3, can help students expand their mathematical knowledge and problem-solving skills. By mastering the base 3 system, students can gain a deeper appreciation for the beauty and complexity of mathematics and develop a stronger foundation for further studies in the field.
