Use the distributive property:
17pi/6 - 2pi = (17/6 - 2) pi. Now, just subtract the fractions as you normally would.
Unfortunately, 2 over 2 minus 1 equals 5 over 6 is just a wrong answer! If it is 2 over 2, minus 1, the answer is that it equals zero. If it is 2, over 2 minus 1, the answer is that it equals 2.
2 minus 2/5 plus 1/2 minus 4 = -1.9
A negative number that is not an integer, of course. Examples are minus 1.5, minus pi, minus square root of 2, etc.
2/5 minus 1/15 is 1/3
It is: 2/7 minus 5/8 is = -19/56
2 pi / 2 = pi.

(pi/2)-1 = 2/pi
2 minus 2/5 plus 1/2 minus 4 = -1.9

Oh, dude, an irrational number less than 0? That's like asking for a vegan steak - it just doesn't exist in the real world! Irrational numbers are those funky ones that can't be expressed as a simple fraction, and they can be positive or negative, but they're always a bit wild and unpredictable. So, yeah, there's no such thing as an irrational number less than 0.
The answer is:cos (pi/2) = 0
2/3 minus 12/15 is -2/15
(pi^2+2pi)/2pi
3/2 minus 2 equals -1/2
2 minus 5/2 equals -1/2
2/5 minus 4/9 equals -2/45
