24/3 = 824/3 = 8

8 + 7 * 2-15 / 5 + 6 * 28 + 7 ∗ 2−15 / 5 + 6 ∗ 2

7 * 2 = 147 ∗ 2 = 14

8 + 14-15 / 5 + 6 * 28 + 14−15 / 5 + 6 ∗ 2

15/5 = 315/5 = 3

8 + 14-3 + 6 * 28 + 14−3 + 6 ∗ 2

6 * 2 = 126 ∗ 2 = 12

8 + 14-3 + 128 + 14−3 + 12

14 + 8 = 2214 + 8 = 22

22-3 = 1922−3 = 19

19 + 12 = 3119 + 12 = 31

Subtract

From left/right.

First, you multiply/divide from left to right.


24/3=8


8+7*2-15/5+6*2


7*2=14


8+14-15/5+6*2


15/5=3


8+14-3+6*2


6*2=12


8+14-3+12

Then, you add/subtract from left to right.


14+8=22


22-3=19


19+12=31

Final answer is 31.

Hope this helps!

Have a nice day! :)
