What integer is the opposite of –6?

The opposite of 6 is -6

This is because they have the same absolute value which means how far it is away from zero. ( the best way to explain is using a number line, I will put below) Absolute value is always shown using positive numbers and the number that it is asking for is put in bars for example, ##|-6|=6##. This means that if you looked on a number line and counted from -6 to 0 it would be 6 counts away. Same with 6. Hope it helped!
