We're confident that we could probably answer that
if we knew what the "opposite" of a number is.
Zero. e.g. The opposite of plus 15 is minus 15 and 15-15 = 0
Why is the opposite of 15 not 1/15 ? It is the reciprocal.
Why is the opposite of 15 not 51 ? It is a mirror.
Likewise, -15 is the "negative of" 15. The opposite of a positive is always a negative.
On a number line, zero is positioned at the center, with positive numbers to the right and negative numbers to the left. The concept of an opposite number means that when you add a number and its opposite, the result is zero. Since zero is neither positive nor negative, its opposite is itself; thus, adding zero to zero results in zero. This visually illustrates that zero is its own opposite on the number line.
Difference. A sum is the result of adding two numbers, and a difference is the result of subtracting two numbers.
Subtract the number you first thought of.
The opposite number of 9 is -9. In mathematics, the opposite of a number is the same distance from zero on the number line, but in the opposite direction. This is denoted by adding a negative sign in front of the number, indicating its direction opposite to the original number.
sum
adding its opposite?
Because of the definition of addition and subtraction. When looking at a real number line: when you add you move to the left or up, when you add the opposite of a number you move in the opposite direction.
it is the same as adding a negative number to a positive number
-7.800000000000001
The result of adding and integer and its opposite is negation. A + (-A) = 0 For all real integers. It has the effect of adding 0 to a sum. Example: 32 + 16 + (-16) + 5 = 37 = 32 + 0 + 5.
Difference. A sum is the result of adding two numbers, and a difference is the result of subtracting two numbers.
Subtract the number you first thought of.
The result of adding 2 to a given number is the sum of the given number and 2.
It is the same as adding a positive and adding a negative number
No - adding an odd quantity of odd numbers will always result in an odd number.
Adding a force acting in one direction to a force acting in the opposite direction is called vector addition, which involves considering the magnitudes and directions of the forces. Adding two numbers is arithmetic addition, where the magnitudes are combined without considering direction.
The opposite number of 9 is -9. In mathematics, the opposite of a number is the same distance from zero on the number line, but in the opposite direction. This is denoted by adding a negative sign in front of the number, indicating its direction opposite to the original number.
