Please help me find the negation of the following:
1)If a>2 and b<-5, then |a|+ |b| >=7
So, I think this can be rewritten as A= a>2 and b<-5; B=|a|+ |b| >=7
and thus, a>2 and b<-5 and |a| + |b|<7
Though, I'm also confused cause it might be:
If a<2 and b>5 OR |a| + |b| >=7.....so as you guys can tell i'm throughly confused.
2) If the numbers a and b are primes, then the number a+b is composite.
Sort of having the same problem as above.
Thanks in advance.
