Are you sure that's right?

11 is prime so only has multiples of 1 and 11, since 1 isn't an option I can't see how this is right.

If there was a minus sign instead of a plus in the bracket you can make it work, or if some of the numbers were negative.

You aren't going mad.

Shouldn't the addition come first therefore that would equal 3+4=7 therefore 11-7=4??

It would be -3+4 to give 1.

Doesn't actually matter which order -+ are done in
