Calculate the quotient in the brackets (if you follow PEMDAS/BEDMAS, brackets come first.)
-4/12 = -0.33
-2/15 = -0.133
This gives you (-0.33)(-0.133)
Next, multiply both brackets together.
(-0.33)(-0.133) = appx. 0.044
Now that you have the product of the two brackets, calculate 5/6
5/6 = 0.833
Finally, sum it all up. Since the last two numbers are negative, we subtract them.
0.833 - 0.33 - 0.133 =
Therefore, the answer is 0.37
