9

The number (-9) is the additive inverse of 9.Inverse operations can also be used to find the additive inverse of a specific number. For example, -9 is the additive inverse of 9 since the sum of -9 and 9 is 0. Additive inverses come in pairs; 9 is the additive inverse of -9, just as -9 is the additive inverse of 9. Any two numbers are additive inverses if they add up to 0.Visualize a pair of additive inverses on the number line. The number 9 and its additive inverse -9 are both nine units away from 0 but on opposite sides of 0. For this reason, -9 is called the opposite of 9, and 9 is the opposite of -9. The opposite of a number may be positive or negative.

9

A negative number. (ex. -9)

It depends on what you mean by an opposite. Every real number has an additive opposite but 0 does not have a multiplicative opposite.

The Opposite of 9 depends on how far you can count up to with the exception of infinity. If you can count up to 100, then the opposite of 9 would be 100 - 9 which is 91. If you can count up to 10000000000, then it is just 10000000000 - 9 which is 9999999991. These are the answers to every number you want the opposite of. You take the number you are thinking of and take that away from the number you can count up to. You may get negative answers too. I can count up to 9999999999999999. this is 999 quadrillion, 999 trillion, 999 billion, 999 million, 999 thousand, 9 hundred and 99. i don't know what comes next. to find the opposite of 9, i just take that away. to give me 9999999999999990. i would gety a negative answert if is said to find the opposite of a googolian (1 with 100 zeroes)! i won't write it out. ----

To subtract a negative number, you must change the subtraction sign to an addition sign, then make the second number its opposite. Ex. (-9)-(-13) (-9)+(+13)=4

In the context of an additive opposite, the answer is -9.
