The opposite of a positive number is negative, and the opposite of a negative number is positive. Since the opposite of 0 is 0 (which is neither positive nor negative), then 0 = 0. The number 0 is the only number that is its own opposite. Whole numbers and the opposites of those numbers are all integers.
The easiest way to remember how to find the opposite of a number is to add a negative sign if the number is positive, or to take away the negative sign if the number is negative.
All positive numbers have their opposite as the same number with a negative value. And, negative numbers like -1, -2, -3, -4 their opposite will be 1, 2, 3, 4 placed left from 0. All negative numbers have their opposite as the same numbers with positive value. Hence, the opposite of zero is itself.
There's no such thing as negative zero. For a binary integer, setting the sign bit to 1 and all other bits to zero, you get the smallest negative value for that integer size. (Assuming signed numbers.) Negative zero is actually used in mathematical analysis, especially in limit calculations.

The additive inverse
For example, the opposite of 4 is -4, or negative four. On a number line, 4 and -4 are both the same distance from 0, but they're on opposite sides.
Opposite numbers are those with opposite signs. So, since 9 is positive, its opposite would be negative. This makes negative 1/9 (-1/9) the opposite reciprocal of positive 9.

Similarly, there is a concept called negative infinity, which is less than any real number. The symbol “-∞” is used to denote negative infinity. Take a close look at this visual display of infinity — positive and negative infinity ride along an infinitely long zip line in opposite directions.
Real Numbers include:
Real Numbers can also be positive, negative or zero.
Additive inverse of a number is a number which when added with the original number gives 0. Therefore, for 1, if we add -1, it gives 0. Therefore, the opposite of 1 is -1.
Positive numbers are greater than 0 and located to the right of 0 on a number line. Negative numbers are less than 0 and located to the left of 0 on a number line. The number zero is neither positive nor negative.
Absolute value is a term used in mathematics to indicate the distance of a point or number from the origin (zero point) of a number line or coordinate system. This can apply to Scalar or vector quantities.
The opposite of -3 is 3.
Videos and solutions to help Grade 6 students know that the opposite of the opposite is the original number. Students understand that, for instance, the opposite of is -5 denoted -(-5) and is equal to 5. In general, they know that the opposite of the opposite is the original number; e.g., -(-a) = a.
Thus, 5 is opposite to 2.
What we'll focus on in this lesson is giving precise meaning to the phrase “infinity times 2 is infinity”.
If a number is multiplied by infinity, then the value of the product is also equal to infinity.
It is impossible for infinity subtracted from infinity to be equal to one and zero. Using this type of math, it would be easier to get infinity minus infinity to equal any real number. Therefore, infinity subtracted from infinity is undefined.
Pi can not be expressed as a simple fraction, this implies it is an irrational number. We know every irrational number is a real number. So Pi is a real number.
The imaginary unit or unit imaginary number (i) is a solution to the quadratic equation . Although there is no real number with this property, i can be used to extend the real numbers to what are called complex numbers, using addition and multiplication.
All non-zero values will be converted to true , and zero values to false . With negative numbers being non-zero, they are converted to true .
The opposite reciprocal of negative 1 is positive 1.
