You can treat these just like you would the addition of any other fractions; you need a common denominator.
pi/2 - pi/3 = 3*pi/6 - 2*pi/6 = pi/6
2*pi - pi/4 = 8*pi/4 - pi/4 = 7*pi/4

Find common denominators in each case. then subtract.
[pi / 2] - [pi / 3]
=[(pi*3) - (pi*2)] / [2*3]
=[3pi - 2pi] / 6
=pi / 6
2pi - pi/4
=[(2*pi*4) - pi] / 4
=[8*pi - pi] / 4
=[7*pi] / 4

pi/2 - pi/3 = 3pi/6 - 2pi/6 = pi/6
2pi - pi/4 = 8pi/4 - pi/4 = 7pi/4

answer in number one: 0.523598775... i used mdas; that is to first either do division or multiplication first before adding or subtracting..
example 18-5*3... the answer is 3 and not 39 since you have to multiply 5 and 3 first before subtracting it from 18
answer in number two: 5.497787114.. i used the same principle...
by the way is used 3.141592654 as the value of pi..
