To find 456-212, Cardell added forward to each number then subtracted Malia subtract two from each number then subtracted will Cardell's Way Malia's way or both ways find the correct answer. Try both ways and show your work. explain why each way works or does not work then find the difference

Answer 1

To find the difference between 456 and 212 using Cardell's way, we would first add forward to each number:
456 + 1 = 457
212 + 1 = 213

Then we subtract the numbers:
457 - 213 = 244

Using Malia's way, we subtract two from each number:
456 - 2 = 454
212 - 2 = 210

Then we subtract the numbers:
454 - 210 = 244

Both Cardell's way and Malia's way yield the same result of 244. Both methods work because adding or subtracting the same value to both numbers does not change their difference.
