Why is division not distributive?

Answered by Frank Schwing

Division is not distributive in the same way that multiplication is because it does not have the same properties as multiplication. The distributive property states that when you multiply a number by a sum or difference, you can distribute the multiplication to each term inside the parentheses. However, when it comes to division, the concept of distributing does not apply in the same way.

To understand why division is not distributive, let’s consider an example. Suppose we have the expression 10 ÷ (3 + 2). If we were to distribute the division, we would divide 10 by both 3 and 2 separately. However, this would not give us the correct result. In this case, we need to first evaluate the sum inside the parentheses (3 + 2 = 5) and then divide 10 by 5. So, the correct answer would be 10 ÷ 5 = 2.

The reason why division does not distribute is because division is an operation that involves splitting or separating a quantity into equal parts. When we divide a number by another number, we are finding out how many times the divisor can be subtracted from the dividend to get an equal or smaller result. Dividing a number by a sum or difference does not have the same concept of breaking apart or separating as multiplication does.

Another way to think about why division is not distributive is by considering the inverse relationship between multiplication and division. Multiplication combines groups or quantities, while division breaks them apart. When we distribute multiplication, we are essentially combining or grouping terms. However, when we distribute division, we are breaking apart or separating terms, which does not align with the concept of division.

In practical terms, let’s say you have 10 apples and you want to divide them equally among 2 friends. You cannot distribute the division by giving each friend 5 apples separately. Instead, you need to divide the total number of apples (10) by the number of friends (2) to determine that each friend gets 5 apples. The division operation does not distribute the apples, but rather determines the equal share for each friend.

Division is not distributive because it does not have the same properties as multiplication. Division involves splitting or separating a quantity into equal parts, while multiplication combines or groups quantities. The concept of distributing does not apply in the same way to division as it does to multiplication.
