Subtraction 2: Testing... Testing...

Great job! Now you know the simple basics of subtraction, and you know how to borrow! Now, we'll practice even more subtraction! This time, instead of me getting you through the problem, I'll give YOU a problem to work on! All right, here we go...

   34

  -27

OK, now that you're done working on this problem, let's give you a grade on a scale of 1-10.

Key

32+ = 1

27-31 = 2

22-26 = 3

17-21 = 4

12-16 = 5

1-3 = 6

4-5 = 7

8-11 = 8

6 = 9

7 = 10

7 is the correct answer. If you got a grade from 1-5, I really recommend www.khanacademy.org.

Thanks for joining me today and I'll see you on the next N2 Math lesson/test!
