A priori/Wittgenstein: expressions that look a priori must be explained. Just as the same expression can be theorem or hypothesis, the same expression can also be equation or hypothesis. We have to distinguish. >a priori,>Identity, >Explanation.
An equation is necessary. It is a rule of grammar and therefore arbitrary (sic).
Error: since it is true that mathematics is a priori, it was believed that there must also be metaphysics a priori.
Equation/Hypothesis/Wittgenstein: 2 + 2 = 4 is a hypothesis in physical space and requires verification. It cannot happen in the field of vision. Four drops of rainwater in two groups of two can only be seen as four drops, while in the physical world they can converge to form one large drop.

WittgensteinVsRussell: but how do we know that they are assigned to each other? One cannot know this and therefore one cannot know whether they are assigned the same number, unless one carries out the assignment, that is, you write them down.
II 354
Moreover, Russell's equal signs can be eliminated, and in this case the equations cannot be written down at all. >Equal sign.
Difference:
Measuring: e.g. numerical equality of classes or
Calculating: e.g. equal number of roots of a 4th degree equation: one is a measurement,
the other a calculation.
Is there an experiment to determine if two classes have the same number? This may or may not be the case for classes that cannot be overlooked.
II 355
It is a damaging prejudice to believe that when using strokes we are dealing with an experiment.
II 409
Def Fundamental Theorem of Algebra/Wittgenstein: according to which each equation has a solution is completely different from the theorem of multiplication: 26x13=419. It seems to be an isolated theorem which has no similarity to the latter.
When we ask whether every algebraic equation has a root, the question has hardly any content.
II 424
If we keep doing the math, it is a matter of physics. The mathematical question refers to the whole equation, not to one side!
Identity/Meaning/Sense/WittgensteinVsFrege/Tractatus: 6.232 The essence of the equation is not that the sides have different meanings but the same meaning. >Intensions, >Meaning.
The actual essence is that the equation is not necessary to show that the two expressions that the equal sign connects have the same meaning, as this can be seen from the two expressions themselves.

Equation/Math/Wittgenstein/Schulte: equations are pseudo-propositions. They do not express thoughts but indicate a point of view - from which you look at the terms in the equation.
