negation

"Can someone explain negation?"
The question is for the following problems write a condition equivalentto the negation of the given condition.
problem a is a>b
(a<>'')AND(a<b)ANDLen(a<5)
(a-d)OR(a=d)

You must have mistyped the question since what you have there doesn't make sense.

"Can someone explain negation?"
The question is for the following problems write a condition equivalentto the negation of the given condition.example,(a<>b)is equivelant to the negation of a=b
problem a is a>b
(a<>'')AND(a<b)ANDLen(a<5)
(a-d)OR(a=d)

I think I have seen this question somewhere before and I believe the actual question should be:

For the following problems, write a condition equivalent to the negation of the given condition. (For example, a <> b is equivalent to the negation of a = b.)

a. a > b

b. (a <> “”) And (a<b) And Len(a) < 5)

c. (a=b) Or (a=d)

And, I agree with MartinLiss that it may not make a lot of sense, but I don't know enough to answer it even if it did make sense.

Hopefully someone else will understand this and be able to help you.

I am sure it is probably one of those things that is real simple if you know it.

Good Luck

Thanks I have reposted the question

Well, I won't do it for you, but I'll tell you how to do it.

To negate an expression, reverse the operators. So, for instance, convert all ANDs to ORs and all ORs to ANDs. Also, convert all = to <>, all <> to =, all > to <=, all < to >=, etc.

By way of example, if the expression were:

(a <> b) OR (b <= c)

The negation would be:

(a = b) AND (b > c)

You should have edited the original post rather than creating a second thread. I've merged the two threads.

Thanks so much that is very helpful.
