Negative numbers are antonyms of positive absolute values. Any positive number preceded by a negative sign is equal to a negative number. On the number axis, negative numbers are to the left of 0, and all negative numbers are less than natural numbers.

Format: such as negative 1 write-1.

Operation format: for example

1.23+(-73)

2.(-84)+(-49)

3.7+(-2.04)

4.4.23+(-7.57)

5.(-7/3)+(-7/6)

6.9/4+(-3/2)

7.3.75+(2.25)+5/4

8.-3.75+(+5/4)+(- 1.5)

9.(- 17/4)+(- 10/3)+(+ 13/3)+( 1 1/3)

10.(- 1.8)+(+0.2)+(- 1.7)+(0. 1)+(+ 1.8)+(+ 1.4)

1 1.(+ 1.3)-(+ 17/7)

12.(-2)-(+2/3)

13.|(-7.2)-(-6.3)+( 1. 1)|

14.|(-5/4)-(-3/4)|-| 1-5/4-|-3/4|)

15.(-2/ 199)*(-7/6-3/2+8/3)

16.4a)*(-3b)*(5c)* 1/6

17.3/7 × 49/9 - 4/3

18.8/9 × 15/36 + 1/27

19. 12× 5/6 – 2/9 ×3

20.8× 5/4 + 1/4

2 1.6÷ 3/8 – 3/8 ÷6

22.4/7 × 5/9 + 3/7 × 5/9

23.5/2 -( 3/2 + 4/5 )

24.7/8 + ( 1/8 + 1/9 )

25.9 × 5/6 + 5/6

26.3/4 × 8/9 - 1/3

It basically contains a lot of formats about negative numbers.

Process format, such as 23 questions

5/2 -( -3/2 + 4/5 )

=5/2 - ( - 15/ 10 + 4/ 10)

=5/2 - ( - 1 1/ 10 )

=25/ 10 + 1 1/ 10

= 14/ 10=7/2 This is the solution of negative fraction, and I wrote it in detail. You should be able to read it, and the others are similar to this one.
