A subtraction sum will contain a minus sign.
it depends how the operation is
because you undo the operation in the equation= to undo subtraction you add
The words "decreased by" suggest the operation of subtraction.
The inverse operation of addition is subtraction. Subtraction undoes addition by taking away a number from the sum to return to the original value.
Addition is the inverse operation to subtraction.
An inverse operation undoes the effect of another operation. For example, addition is the inverse operation of subtraction, and multiplication is the inverse operation of division. Applying an operation and its inverse leaves you with the original value.
Subtraction
Subtraction can be seen as the inverse operation to addition.
Inverse means opposite. What undoes subtraction? Addition undoes subtraction!
1. subtraction 2. all mathematical operations 3. multiplication 4.division has no inverse operation
Subtraction is definitely an operation defined on real numbers. I'm guessing you are actually asking why subtraction is not included as a commutative operation, this is because a-b is not always equal to b-a.
