- Q: what does constant, inverse operations, and additive inverse mean in 8th grade math terms. :)?
- Constant means something that does not change. For example, 3 is a constant, because 3 is always 3. The expression x + 5 is not a constant, because it changes depending on what the value of x is. Usually, when talking about expressions, constant just means that it's a number. Examples of constants include 3, 7, 11.578, 12/25, and pi. If you have discussed functions: you can also say a function is constant if it always outputs the same value no matter what its input is. For example, the function f(x) 7 is constant. Inverse operations are operations which, in a sense, undo each other. For example, multiplication and division are inverse operations. If I multiply something by 3 and then divide it by 3, I'll always get the same number back: 7 * 3 / 3 7 12 * 3 / 3 12 100 * 3 / 3 100 The same holds if I multiply then divide by any other number: 7 * 12 / 12 7 12 * 800 / 800 12 etc. Additive inverse just means the negative of a number. For example, the additive inverse of 7 is -7; the additive inverse of 12 is -12. Careful, though; the additive inverse of -5 is 5, because -(-5) 5. (The additive inverse of 0 is 0.) It is called the additive inverse because if you add a number to its additive inverse, they cancel each other out and you get zero: 7 + (-7) 0 12 + (-12) 0 -5 + 5 0 0 + 0 0. (This is the same sort of inverse meant in inverse operations--except instead of looking at an operation that undoes another operation, we're looking at a number which, when we add it to the original number, they cancel and we get zero.)

- Q: i just bought a bottle of lucas transmission fix for my k5 blazer. when i add this to the fluid do i have to take some transmission fluid out, or just pour the bottle in.
- Trans additives do not correct a trans problem. At best they will mask it while the trans self destructs. If you had ever had to rebuild a trans that has had that stuff put in it, you wouldn't even think about using it. Get the tranny checked by a professional
