Best Answer

I have a new way in checking answers in subtraction. If you have the answer, subtract the minuend to the difference then, if the answer is the subtrahend the answer is correct. Here is an example.

E.g.

13738724-11234689=2504035

Check = 13738724(the minuend)-2504035(the answer)= 11234689

Another simple example.

E.g.

67-23=44

Check= 67(minuend)-44(answer)=23(subtrahend)

Thanks and God Bless You!

NOTE: I do not know if anyone also knows this trick!
