Sage 9.4 does not work on M1 Macs, you need to use the development
version (and I am not 100% sure about the
exact status of the support of M1, see https://trac.sagemath.org/ticket/30592)
One of the culprits is indeed gpm, one needs gmp 6.2.1 (which is in
the current beta)

Sage can “distribute” many operations on equalities operands, such as :
sage: var("a, b")
(a, b)
sage: (a==b)+3
a + 3 == b + 3
sage: 3*(a==b)
3*a == 3*b
sage: (a==b)^3
a^3 == b^3
But not common functions :
sage: log(a==b)
log(a == b)
sage: sin(a==b)
sin(a == b)
In both cases above, “distribut
I see. So the difference between this and, say, 1+1==2 (which returns
True) is that 1+1 and 2 are numbers, not symbolic things.

Thank you, that works. What is strange is that this does not:
sage: right=integrate(integrate(sin(x^2),y,0,x),x,0,1) sage:
wrong=integrate(integrate(sin(x^2),x,y,1),y,0,1) sage:
real(wrong)==right -1/2*cos(1) + 1/2 == -1/2*cos(1) + 1/2
Is Sage seeing a difference there that I don't?
I think
You can compare the real and imaginary parts directly.

sage: bool(wrong.real() == right)
True
sage: wrong.imag()

I was showing my students a famous calculus example of an integral that
can be computed in one order of the variables but not in the other.
Knowing that SageMath can compute anything, the students suggested
trying the integral the "wrong" way.
The "right" way is
