What is the inverse operation of adding 11?
A. dividing by 11
B. subtracting 11
C. multiplying by 11
D. adding 11
Answer (2)
The inverse operation undoes the original operation.
Adding 11 is represented as x + 11 .
Subtracting 11 undoes adding 11: ( x + 11 ) − 11 = x .
The inverse operation of adding 11 is subtracting 11, so the answer is subtracting 11. s u b t r a c t in g 11
Explanation
Understanding Inverse Operations The question asks us to identify the inverse operation of adding 11. In mathematics, an inverse operation is an operation that reverses the effect of another operation. For example, addition and subtraction are inverse operations of each other, and multiplication and division are inverse operations of each other.
Finding the Inverse To determine the inverse of adding 11, we need to find an operation that, when applied after adding 11, returns the original value. Let's represent a number as x . Adding 11 to x gives us x + 11 . To undo this addition, we need to subtract 11 from the result: ( x + 11 ) − 11 = x .
Conclusion Therefore, the inverse operation of adding 11 is subtracting 11.
Examples
Imagine you're baking a cake and accidentally add too much sugar (11 extra grams). To correct this, you need to remove the excess sugar (subtract 11 grams). Similarly, in mathematics, subtraction is the inverse operation of addition, allowing you to 'undo' the addition and return to the original amount.
The inverse operation of adding 11 is subtracting 11. This means that if you add 11 to a number and then subtract 11, you return to the original number. Therefore, the correct choice is option B: subtracting 11.
