• Why is 2/2 equal to 1 but 1/1 is not 2?

    The question about why ( \frac{2}{2} ) equals 1 but ( \frac{1}{1} ) is not 2 can be understood by exploring basic principles of arithmetic and division.

    In mathematics, division is defined as distributing a number or quantity into equal parts. The expression ( \frac{2}{2} ) represents a division of 2 by 2, which results in 1, because dividing any number by itself results in 1 (except when the number is zero, which cannot be divided by itself). This follows the basic arithmetic rule that a number divided by itself is one.

    On the other hand, ( \frac{1}{1} ) results in 1 because 1 divided by itself is also 1. The concept that doesn't allow ( \frac{1}{1} ) to equal 2 is the principle of consistency within the logical framework of arithmetic: each operation based on defined rules must result in only one outcome, barring any mistakes or different contexts.

    For additional context, it's insightful to note how mathematical concepts vary based on different interpretations or systems. For instance, Ellen Langer in the explains how arithmetic operations like 1 + 1 can result in different outcomes based on context, yet this doesn't change fundamental arithmetic laws like division remaining consistent by definition 1.
