Hello, I'm 14 years old, I'm currently in 8th grade and I'm practicing math so answer here if I'm right.
X + X = 2X
X × X = X²
X + Y = XY
Am I right?

X + X = 2X
X × X = X²
X + Y = X + Y (not XY)
X × X = X²
X + Y = X + Y (not XY)

X+Y=X+Y=/= XY the third one is wrong.

X + X = 2X
X * X = X²
X + Y = X+Y
X * Y = XY
X * X = X²
X + Y = X+Y
X * Y = XY

Not quite because X + Y = X + Y and not XY

X + X = 2x correct!
X * X = X^2 correct
X + Y = XY wrong! it should be X + Y
X * X = X^2 correct
X + Y = XY wrong! it should be X + Y

X+X=2X
X*X=X^2
X+Y=X+Y NOT X*Y
XY=X*Y
X*X=X^2
X+Y=X+Y NOT X*Y
XY=X*Y
