Why would you use addition to solve a subbtraction problem?
Addition can be used to solve a subtraction problem by using the concept of inverse operations. By adding the opposite of a number to another number, the result will be the same as subtracting the first number from the second number. This can be helpful in mental math or when trying to simplify complex subtraction problems.
How would you describe the order of operations to solve any given problem?
