Answer 2

It appears there are some incorrect equations in your statement. Let's correct them:

1. 7 + 5 = 12 (This is correct)
2. 8 - 6 = 2 (This is correct)
3. 9 + 8 = 17 (This is correct)
4. 16 - 9 = 7 (This is correct)
5. 90 - 40 = 50 (This is correct)
6. 60 + 30 = 90 (This is correct)
7. 14 - 4 - 3 = 7 (This is correct)
8. 13 - 9 + 8 = 12 (This is correct)

So, most of the equations are correct, but there is one mistake in equation 6. It should be 60 + 30 = 90, not 60 + 30 = 714.
