Evaluate Each Expression Below. Click On Undefined As Needed.${ \begin{array}{c} 0 \div 9 = \square \ \frac{0}{2} = 0 \end{array} }$
Introduction
In mathematics, expressions are used to represent a value or a relationship between values. Evaluating an expression involves substituting the values of the variables and performing the necessary operations to obtain the final result. In this article, we will evaluate two expressions and discuss the results.
Expression 1: 0 ÷ 9
Undefined or Not?
When we divide 0 by 9, we are essentially asking how many times 9 fits into 0. However, 9 cannot fit into 0 because 0 is a number that represents the absence of quantity. Therefore, the result of 0 ÷ 9 is undefined.
Why is 0 ÷ 9 undefined?
In mathematics, division is defined as the inverse operation of multiplication. When we divide a number by another number, we are essentially asking how many times the divisor fits into the dividend. However, when the dividend is 0, the divisor cannot fit into it because 0 is a number that represents the absence of quantity. Therefore, the result of 0 ÷ 9 is undefined.
Why is 0 ÷ 9 not equal to 0?
Some people may argue that 0 ÷ 9 is equal to 0 because 0 is a multiple of 9. However, this is not correct. When we divide 0 by 9, we are not asking how many times 9 fits into 0, but rather how many times 9 fits into a quantity that is equal to 0. Since 9 cannot fit into 0, the result of 0 ÷ 9 is undefined.
Expression 2: 0/2
The Result of 0/2
When we divide 0 by 2, we are essentially asking how many times 2 fits into 0. However, 2 cannot fit into 0 because 0 is a number that represents the absence of quantity. Therefore, the result of 0/2 is 0.
Why is 0/2 equal to 0?
In mathematics, division is defined as the inverse operation of multiplication. When we divide a number by another number, we are essentially asking how many times the divisor fits into the dividend. However, when the dividend is 0, the divisor can fit into it any number of times because 0 is a number that represents the absence of quantity. Therefore, the result of 0/2 is 0.
Why is 0/2 not undefined?
Some people may argue that 0/2 is undefined because 2 cannot fit into 0. However, this is not correct. When we divide 0 by 2, we are not asking how many times 2 fits into 0, but rather how many times 2 fits into a quantity that is equal to 0. Since 2 can fit into 0 any number of times, the result of 0/2 is 0.
Conclusion
In conclusion, the result of 0 ÷ 9 is undefined, while the result of 0/2 is 0. This is because division is defined as the inverse operation of multiplication, and when the dividend is 0, the divisor cannot fit into it in the case of 0 ÷ 9, but can fit into it any number of times in the case of 0/2.

Introduction
In the previous article, we evaluated two expressions and discussed the results. In this article, we will answer some frequently asked questions (FAQs) about evaluating expressions.
Q: What is the result of 0 ÷ 9?
A: The result of 0 ÷ 9 is undefined. This is because division is defined as the inverse operation of multiplication, and when the dividend is 0, the divisor cannot fit into it.
Q: Why is the result of 0 ÷ 9 undefined?
A: The result of 0 ÷ 9 is undefined because 9 cannot fit into 0. When we divide 0 by 9, we are essentially asking how many times 9 fits into 0. However, 9 cannot fit into 0 because 0 is a number that represents the absence of quantity.
Q: What is the result of 0/2?
A: The result of 0/2 is 0. This is because when we divide 0 by 2, we are essentially asking how many times 2 fits into 0. However, 2 can fit into 0 any number of times because 0 is a number that represents the absence of quantity.
Q: Why is the result of 0/2 equal to 0?
A: The result of 0/2 is equal to 0 because 2 can fit into 0 any number of times. When we divide 0 by 2, we are not asking how many times 2 fits into 0, but rather how many times 2 fits into a quantity that is equal to 0.
Q: What is the difference between 0 ÷ 9 and 0/2?
A: The difference between 0 ÷ 9 and 0/2 is that the result of 0 ÷ 9 is undefined, while the result of 0/2 is 0. This is because division is defined as the inverse operation of multiplication, and when the dividend is 0, the divisor cannot fit into it in the case of 0 ÷ 9, but can fit into it any number of times in the case of 0/2.
Q: Can we divide any number by 0?
A: No, we cannot divide any number by 0. Division is defined as the inverse operation of multiplication, and when the dividend is 0, the divisor cannot fit into it.
Q: What is the result of 1 ÷ 0?
A: The result of 1 ÷ 0 is undefined. This is because division is defined as the inverse operation of multiplication, and when the dividend is 0, the divisor cannot fit into it.
Q: What is the result of 2 ÷ 0?
A: The result of 2 ÷ 0 is undefined. This is because division is defined as the inverse operation of multiplication, and when the dividend is 0, the divisor cannot fit into it.
Q: Can we divide a fraction by 0?
A: No, we cannot divide a fraction by 0. Division is defined as the inverse operation of multiplication, and when the dividend is 0, the divisor cannot fit into it.
Q: What is the result of 1/0?
A: The result of 1/0 is undefined. This is because division is defined as the inverse operation of multiplication, and when the dividend is 0, the divisor cannot fit into it.
Q: What is the result of 2/0?
A: The result of 2/0 is undefined. This is because division is defined as the inverse operation of multiplication, and when the dividend is 0, the divisor cannot fit into it.
Conclusion
In conclusion, we have answered some frequently asked questions (FAQs) about evaluating expressions. We have discussed the results of various expressions, including 0 ÷ 9, 0/2, 1 ÷ 0, 2 ÷ 0, 1/0, and 2/0. We have also discussed why the results of these expressions are undefined.
