How to calculate the subtraction of two negative fractions It is best to be specific Thank you

For example: -5-(-3)=-5+3=3-5=-2, negative negative becomes positive, that is, subtracting a negative number is equal to adding his positive number. For example: -(3)=3. Multiplying two negative numbers is also negative and negative.

Fractions (from Latin.

Broken") represents a part of the whole, or more generally, any part of an equal number. When speaking in everyday English, fractions describe parts of a certain size, such as half, five-eighth, three-quarter.

Error-prone. 1.When judging whether a number is a negative fraction, it must be judged according to its original form.

Example: 4 2 is a negative fraction because 4 2 is equal to 2 after the approximation of the minute, but the meaning is completely different. There are true and false scores in the score.

True scores also include the average true score and the minimum true score. 4 2 is a negative general true fraction, and it is a fraction. But it can't be said to be an integer.

2.Because all numbers can be written as a number to 1, it is generally accepted that a number in the form of a minus a few is not a negative fraction.

3.There are fractions in inequalities.

to consider its symbol.

The subtraction of two negative numbers, such as -a -b, is equivalent to the absolute value of the minus plus the subtracted number, that is, -a minus -b is equal to -a+b, and the specific process with the operator symbol is: -a-(-b)=-a+b.

The subtraction of two negative fractions becomes the absolute value of the next fraction minus the absolute value of the previous negative fraction, and continues to be done using the denominator method.

Direct addition (with symbolic operations)!

Question 1: How to calculate the subtraction of two negative numbers that are not the same? Fig.

Question 2: How do you calculate the subtraction of two negative numbers? For example, (-3)-(5) and (-8)-(4) tell us how to calculate the minus, negative and positive. For example: (-3)-(5)=-3 ten-5=2, (-8)-(4)=-8+4=-4

Problem 3: Find positive and negative. Two negative numbers, do they add or subtract? Let's take a list of -4 and -3

When added, it's actually -4+(-3)=-7

And when subtracting, -4-(-3)=-4+3=-1 (formula: negative negative is positive, that is, it is preceded by a minus sign, and the parentheses need to be changed to remove the parentheses).

Question 4: How is the addition, subtraction, multiplication and division of negative numbers calculated? An example might be more clear, as follows:

2+(-5)=-2+5)=-stroke.

2x(-5)=2x5=10

Multiplication and division, if they are both negative, are no different from positive numbers, and negative negative is positive.

Question 5: How to calculate the subtraction of three negative numbers without parentheses You can put forward the -sign, and it becomes the addition of three positive numbers, and then find the opposite number.

For example, -1-5-7=-(1+5+7)=-13

Discussion on a case-by-case basis:

Knowing two negative numbers, then.

1) When a>b, a-b>0;

2) When a=b, a-b=0;

3) When a

Add. For example:

4 5 = (-4) + (-5) = -9

Addition and subtraction of positive and negative numbers:

Add two numbers of the same sign, take the same symbol, and add their absolute values.

The two numbers of different numbers are added to take the sign of the number with the larger absolute value, and the bridge dust with the larger absolute value is used to subtract the smaller absolute value.

The two numbers of different numbers are subtracted, and the negative and negative are positive.

The addition and subtraction of any number of vohu zeros is equal to the original number.

Minusia: Negative and negative.

For example: (-3)-(5)=-3 ten-5=2, (-8)-(4)=-8+4=-4

Negative number] 1, negative number is a mathematical term, negative number and positive number indicate the opposite meaning of the quantity. Negative numbers are marked with a minus sign"-"and a positive number marker, such as 2, which represents the opposite of 2. As a result, any positive number preceded by a negative sign becomes a negative number.

A negative number is the opposite of its absolute value. On the number axis, negative numbers are on the left side of 0, and the earliest record of negative numbers is the ancient mathematical work "Nine Chapters of Arithmetic" in China. It is specified in the calculation"Positive is red, negative is black", that is, the red arithmetic chip is used to represent a positive number, and the black number is a negative number.

The two negative numbers are compared to the size, and the absolute value is larger than the smaller.

2. Any positive number preceded by a negative sign is equal to a negative number. 0 plus a negative sign is not a negative number! On the number axis, the negative numbers are all to the left of 0, there is no smallest negative number, all negative numbers are smaller than the natural number and the number smaller than zero (<0).

Marked with a minus sign (i.e., equivalent to a minus sign). For example: -1 is a negative number, which reads: minus 1.

Minusia: Negative and negative. For example: (-3)-(5)=-3 ten-5=2, (-8)-(4)=-8+4=-4

Let's take a list of -4 and -3

When added, it's actually -4+(-3)=-7

And when subtracting, -4-(-3)=-4+3=-1 (formula: negative negative is positive, that is, it is preceded by a minus sign, and the parentheses need to be changed to remove the parentheses).

The addition of two negative numbers must be negative, the multiplication and division must be positive, and the subtraction may be negative or positive.

Add for example:

Addition and subtraction of positive and negative numbers:

Add two numbers of the same number, take the same symbol, and add their absolute values Add two numbers of different numbers to take the sign of the number with the greater absolute value, and subtract the smaller absolute value with the larger absolute value.

The two numbers of different numbers are subtracted, and the negative and negative are positive.

Zero plus or minus any number is equal to the original number.

Let me give you an example: (10)-(10)=(10)+10 =0

The two negative numbers are subtracted, and the negative number that has been subtracted by the sedan silver becomes a positive number.
