Step-by-step explanation:

We have plenty of equations here, so let's make it quick.

Use the PEMDAS formula, which means to add and subtract from left to right :

4 + 10 + 8

4 + 10

14 + 8

22

5 - 9 + 1

-4 + 1

-3

-8 - 2 + 3

-11 + 3

-7

-15 + 8 - 7

-15 + 1

-14

24 + 6 - 12

30 - 12

18

-14 - 3 - 6 - 1

-17 - 6 - 1

-23 - 1

-24

-4 + 5 + 6 + 3 - 9

1 + 6 + 3 - 9

7 + 3 - 9

10 - 9

1

-1 + 2 - 4 - 6 - 3 - 8

1 - 4 - 6 - 3 - 8

-3 - 6 - 3 - 8

-9 - 3 - 8

-12 - 8

-20

2 - 10 - 6 + 14 - 1 + 20

-8 - 6 + 14 - 1 + 20

-14 + 14 - 1 + 20

-1 + 20

19

-13 - 1 - 2 - 8 + 4 - 6 - 10

-14 - 2 - 8 + 4 - 6 - 10

-16 - 8 + 4 - 6 - 10

-24 + 4 - 6 - 10

-20 - 6 - 10

-26 - 10

-36

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8

thats one
