Answer:
466 + 68
Step-by-step explanation:
We can easily check a subtraction problem with an addition problem.
Calculate the sum of the subtracted and the difference. If the sum is equal to the minuend in the original subtraction problem, the answer is correct.
Minuend - Subtrahend = Difference
466 + 68 = 534
The statement '534 – 68 = 466' is correct.
Hope this helps.
