  Can you explain how that is? Like with an example?

  I’m not sure what you’re asking about. Explain what with an example?

  Math is exactly like English. It’s a language

  No it isn’t. It’s a tool for calculating things, with syntax rules. We even have rules around how to say it when speaking.

  It’s an abstraction to describe something

  And that something is the Laws of the Universe. 1+1=2, F=ma, etc.

  Hell the word statement is used in math and English for a reason

  You won’t find the word “statement” used in Maths textbooks. I’m guessing you’re referring to Expressions.

    Those rules are based on axioms which are used to create statements which are used within proofs. As far as I know statements are pretty common and are a foundational part of all math.

    Defining math as a language though is also going to be pointless here. It’s not really a yes or no thing. I’ll say it is a language but sure it’s arguable.

    And again laws are created using statements. I have plenty of textbooks that contain “statements”

      Those rules are based on axioms

      Nope! The order of operations rules come from the proof of the definitions in the first place. 3x4=3+3+3+3 by definition, therefore if you don’t do the multiplication first in 2+3x4 you get a wrong answer (having changed the multiplicand).

      As far as I know statements are pretty common

      And yet you’ve not been able to quote a Maths textbook using that word.

      are a foundational part of all math

      Expressions are.

      It’s not really a yes or no thing

      It’s really a no thing.

      And again laws are created using statements

      Not the Laws of Maths. e.g. The Distributive Law is expressed with the identity a(b+c)=(ab+ac). An identity is a special type of equation. We have…

      Numerals

      Pronumerals

      Expressions

      Equations (or Formula)

      Identities

      No statements. Everything is precisely defined in Maths, everything has one meaning only.
