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.
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.
A rational number is always the result of dividing an integer when the divisor is nonzero.
Subtracting rational numbers involves managing fractions, which may require finding a common denominator, while subtracting whole numbers is a straightforward process of simple arithmetic. Additionally, rational numbers can result in negative values or fractions, affecting the outcome and interpretation of the result. In contrast, whole numbers are always non-negative integers, making their subtraction simpler and more predictable. Thus, the complexity of operations increases with rational numbers due to their fractional components.
When subtracting one fraction to another, one or both fractions are renamed so that they have the same denominators. Then the result of the subtraction is the equal to the subtraction of the numerators divided by the common denominator.
Just multiply 209 by any integer. The result is - by definition - a multiple of 209.
When subtracting integers, the result is equivalent to adding the opposite of the integer being subtracted. Specifically, for any integers ( a ) and ( b ), the statement ( a - b ) can be rewritten as ( a + (-b) ). This means that subtracting an integer is always the same as adding its negative.
adding its opposite?
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.
Subtracting integers involves changing the subtraction operation to addition by using the additive inverse. For example, subtracting a positive integer is the same as adding its negative counterpart. Additionally, when subtracting two integers with different signs, the result is determined by finding the difference of their absolute values and applying the sign of the integer with the larger absolute value. Lastly, subtracting a negative integer effectively increases the value, as it is equivalent to adding a positive integer.
When you subtract a negative integer from another integer, the result is greater than the original integer. This is because subtracting a negative is equivalent to adding its positive counterpart. For example, subtracting -3 from 5 (5 - (-3)) is the same as adding 3, resulting in 8, which is greater than 5.
Subtracting an integer is the same as adding its opposite.Examples:In the following examples, we convert the subtracted integer to its opposite, and add the two integers.7 - 4 = 7 + (-4) = 312 - (-5) = 12 + (5) = 17-8 - 7 = -8 + (-7) = -15-22 - (-40) = -22 + (40) = 18Note that the result of subtracting two integers could be positive or negative.

When subtracting two positive integers, the result can be either a positive integer, zero, or a negative integer, depending on the values of the integers involved. If the first integer is larger than the second, the result is positive. If the two integers are equal, the result is zero. However, if the first integer is smaller than the second, the result will be negative, indicating the need for a different context, such as using absolute values or considering negative integers.
When you add an integer and its opposite, the result is always zero. This is because the opposite of an integer is the same number with the opposite sign, effectively canceling it out. For example, if you take 5 and its opposite, -5, their sum is 5 + (-5) = 0. Thus, the addition of any integer and its opposite yields a sum of zero.
Yes because you are always adding.
To subtract integers, you can think of subtraction as adding the opposite. For example, to subtract a positive integer, you add its negative counterpart. If you have a negative integer, you add its positive counterpart instead. This approach helps simplify the operation and determine the result based on the rules of adding positive and negative numbers.
