ELI5: Explain Like I'm 5

Negation

Negation means saying the opposite of something. Let's say you like ice cream, but your friend does not like ice cream. Your friend is using negation. They are saying the opposite of what you like.

In math, negation means to change a positive number to a negative number or a negative number to a positive number. For example, if you have the number 5, the negation of 5 would be -5, and if you have the number -3, the negation of -3 would be 3.

It's like a magic trick where you switch the number to the opposite side of the number line. This can help when you are solving problems in math or figuring out if something is true or false.

So remember, negation is just when you say the opposite of something or when you switch a number to the opposite side of the number line.
