It depends on your definition of 1

#

in binary 1 + 1 = 10

so first we carry the one from the other ones because the other two ones got in an argument and arent friends now so the third one makes of them friends so the answer is probally 5129

0 = 0

20 = 20

36 - 16 = 45 - 25

16 - 36 = 25 - 45

16 - 36 + 81/4 = 25 - 45 + 81/4

4² - 2 * 4 * 9/2 + (9/2)²=5² - 2 * 5 * 9/2 + (9/2)²

Now I use the binomial formula: (a+b)²=a²+2ab+b²

(4 + 9/2)² = (5 + 9/2)²

4 + 9/2 = 5 + 9/2

4 = 5

2 + 2 = 5

that's incredibly stupid

#

I excepted something at least kinda hard to spot the mistake

#

Wrong use of binomial formula

#

4² - 2 * 4 * 9/2 + (9/2)²=(4-9/2)^2

#

And it's not always true that if a^2=b^2, then a=b

#

Which would be the mistake if you expanded it correctly

#

All of it can be simplified
1-2=-1
(1-2)^2=(-1)^2
(1-2)^2=1
1-2=1
-1=1
0=1
