Answer:
1. Yes, because 1 minus 3 can't happen, since 3 is bigger than 1.
2. No, because 6 minus 4 can happen, since 6 is bigger than 4.
3. No, because 9 minus 5 can happen, since 9 is bigger than 5.
4. Yes, because 5 minus 8 can't happen, since 8 is bigger than 5.
5. Yes, because 0 is nothing, and you can't subtract a number bigger than it by it.
6. No, because a number can be subtracted by itself to get 0.
Step-by-step explanation:
When you subtract 2 numbers, you have to sometimes carry a number over to the first digit (meaning put the number that you had over the first digit of the first number). Here is an example:
5 67 17
-29
36
You have to subtract, and since 7 is smaller than 9, you have to borrow 10 from the 6 in 67, so that you add 10 to 7, to make 17, which is bigger than 9 and can be subtracted. When you do that, you get 6, so you put the 6 down, and cross out 6 to make it 5, since it is in the 10ths place, it makes sense to change it to 5. Subtarct the numbers, and you get your answer!
I hope this helps :)
