8 + 8 + 6 + 3 + 4 + 3 = 32
3 + 4 + 2 + 8 + 6 + 0.3 + 4 + 2 + 8 + 6 + 0.3 + 4 + 2 = 49.6
6 + 4 + 3 + 4 + 4 + 5 + 4 + 6 + 5 + 4 + 8 + 4 = 57
2 + 4 + 6 + 8 + 0.300 = 20.300
-1-8+4-(-6?
2 + 4 + 8 + 6 + 3 + 7 + 9 + 8 = 47
4 + 5 + 6 + 7 + 8 + 9 = 39
9 + 8 + 7 + 6 + 5 + 4 = 39
(1/6) + (4/6) + (4/8) = (5/6) + (4/8) = (5/6) + (3/6) = 8/6 = 4/3 = 1 and 1/3

You can plug it into your calculator. Otherwise, do 8-6, then take that answer and subtract 4. 8-6-4 = -2. Or you can say 8-6 = 2, and 2-4 = -2. The answer is -2
6 - 4 + 8 - 9 = 1
