Estimation is a important skill to know when adding and subtracting decimals because if you estimate you have an idea on what your answer should be close to. 
For example 4.68-2.38 could be 5-2 which is 3. 4.68-2.38 equals 2.3. 2.3 is close to 3.

vvvvv 
Step-by-step explanation:
 I suspect two 8 means 8x2, but if it means 2+8, I'll add another answer.
1. 8x2= 16 + 5/6(.83) = 16.83 = 50-16.83= 33.17
ORRRRR
2. 2+8=10+.83= 10.83 = 39.17
