Answer 1

I can read only one option unambiguously: (7 − 4) − 4 = 3 − 4 = −1, so that one is correct.

The other choices in your message are ambiguous because superscripts/fractions didn’t copy clearly. Can you retype the other options using plain-text notation? For example:
- use ^ for exponents: 7^2, 7^0
- use / for fractions: 1/7
- use parentheses and * for multiplication if needed

Once you paste them in that form I’ll evaluate and pick the second expression that equals −1.
