Hello M8!

You Are Gonna Get Some!

Lets Take A Look, Shall We?
(3-2²) + 5 = 3² - 5
2² = 4
(3 - 4) + 5 = 3² - 5
3² = 9
(3 - 4) + 5 = 9 - 5
3 - 4 = -1
9 - 5 = 4
-1 + 5 = 4
-1 + 5 = 4
Is This A True Statement:
4=4
Yes, So The Answer For Number One Is Yes.
(1/2)²−1/2 = −0.25 
1/2² = 1/4 = 0.25
1/2 = 0.5.
0.25 - 0.5 = -0.25
Is This True? 
Yes, So The Answer For Number Two Is Yes.
8²+16÷2 = 80/2
80/2 = 40
8² = 64
16÷2 = 8
64 + 8 = 40
64 + 8 = 72
72 = 40
Is This True?
No, So The Answer For Three Is No.
(1/3)² = 8/9−7/9
1/3² = 1/6
8/9 - 7/9 = 1/9
1/6 = 1/9
Is This A True Statement?
No, So The Answer For 4 Is No. 
I Hope This Helps, M8!
