I don't know if it's what you want, you can refer to it. You calculate the answer yourself. 1, calculation: (1)-5-9+3; (2) 10- 17+8; (3)-3-4+ 19- 1 1; (4)-8+ 12- 16-23.2. Calculation: (1)-4.2+5.7-8.4+10; (2)6. 1-3.7-4.9+ 1.8; 3. Calculation: (1) (-36)-(-25)-(+36)+(+72); (2)(-8)-(-3)+(+5)-(+9); (3) -9+(-3 )+3 ; 4.

The farther away from the origin 4. The correct number for the following statement is 1. If the reciprocal of a number is itself, then the number is 0.2. If the absolute value of a number is itself, then the number is 0.3. If "the absolute value of a number is negative", then this sentence is wrong. 4 If the absolute value of a number is its inverse, then the number is negative A. 1 B.2 C.3 D.4 2, fill in the blanks 1. The difference between the actual diameter size of a table tennis ball and the standard diameter size is minus 0.0 1mm, and its practical significance is () 2. The number represented by a on the number axis is negative 3. Then the distance from point A to origin O is () 1. Select 1. A is 3 years older than B. B is 3 years older than B. B is 3 years older than B. B is 3 years older than A. D is 3 years younger than A. Negative 2 corresponds to point a on the number axis. Then the number represented by a point with a distance of not more than 2 is a.2b.3c.5d. There are countless 3s. The rational number m is greater than n, corresponding to points m and n on the number axis respectively. In the following cases, point A is on the right side of the origin, point N is on the left side of the origin, and point B is on the left side of the origin. Point n is to the right of the origin. C. points m and n are on the left of the origin. D. points m and n are on the right of the origin. 4. If the absolute value of a-3 is -3+a=0, the range of a is A.a less than or equal to 3 B.a less than 3 C.a greater than or equal to 3 D.a greater than or equal to 1, and the cube of a number is equal to itself. This number is () a, 0 B, 1 C,-1, 1 D,-1, 1, 0 2. In the following categories, the inequalities are () a, (-3) 2 and. (-1) 200+(-6543331/2,-1/3,1/4,-1/5,1/6 ... Then these two numbers are equal to C. If a number is negative, then the absolute value of this number is its opposite number D. The greater the absolute value, the greater the number. 6. Comparing the sizes of-1/5 and-1/6, the result is () a, > b, 0, then there must be () a, m > 0b, m < 0c, m = 0d. None of the above is true. 9. Compared with its reciprocal 1/n and its reciprocal -n, a positive integer n is exactly () a, -n ≤ n ≤ 1/nb, -n < 1/n < NC,1/n < n.
