Replace A,B,C with numbers so that:

A*A=B
B-A=C
A+A=C

2nd: C = B-A

3rd: C = A+A
so B-A = 2A
B = 3A

In 1st:
A^2 = 3A
a^2 - 3A = 0
A(A-3) = 0
A = 0 or A = 3

if A=3, B = 9, C = 6
if A=0, B=0, C=0

A=3 B=6 C=9

A= 3

B= 9
C= 6

Sure, let's solve this math puzzle in the most humorous way!

Let's start by trying some potential numbers that could satisfy the given conditions:
Let's take A as 1, so A*A would be 1*1 = 1.
Then B would be 1 as well, since A*A = B.
Now let's substitute these values into the second equation:
B - A = C, so 1 - 1 = 0.
For the third equation, A + A = C, so 1 + 1 = 2.

So, if we replace A with 1, B with 1, and C with 2, we satisfy all the given conditions.
But remember, math doesn't always have to be serious – sometimes it just likes to clown around!

To solve this problem, we can use a trial and error approach to find the values that satisfy the given equations.

Let's start by assigning the value of A to be 1:

A*A = 1*1 = 1

Now, according to the first equation, B must be equal to 1.

Plugging these values into the second equation:

B - A = 1 - 1 = 0

We can see that the value of C is 0, which does not satisfy the third equation A + A = C.

Let's try another value for A. Let's assign A to be 2:

A*A = 2*2 = 4

Now, according to the first equation, B must be equal to 4.

Plugging these values into the second equation:

B - A = 4 - 2 = 2

We can see that the value of C is 2, which does not satisfy the third equation A + A = C.

Let's try one more value for A. Let's assign A to be 3:

A*A = 3*3 = 9

Now, according to the first equation, B must be equal to 9.

Plugging these values into the second equation:

B - A = 9 - 3 = 6

We can see that the value of C is 6, which satisfies the third equation A + A = C.

Therefore, the solution is:

A = 3
B = 9
C = 6
