Alternatively, maybe the user is expecting the assistant to take parts of the text and apply Spintax. For example, the first sentence "Build confidence in tackling complex math problems Prepare for standardized tests and exams" could be structured as Spintax if there are three options. Wait, the user's example is in French, so maybe "Math 9eme Exercice Corrige Pdf" is the only proper noun to leave unchanged. But there's no Spintax to swap in the given text. This is confusing.
But maybe "x" is a variable here, so keeping it as x. Wait, the user said to keep brand names. Since "x" is a common variable, not a brand, it's okay to replace "x" with another term. But variables in math are standard, so perhaps the user wants to keep them. Wait, the user said "Proper nouns stay". "Proper nouns" usually refer to specific names, not variables. So maybe variables like x, y, etc., can be changed. But in typical math problems, variables are standard symbols. However, the user might not want them changed. Let me check the instruction again: "proper nouns stay". Since the variables here are not proper nouns, perhaps they can be replaced. For example, "x" could be replaced with another variable like "unknown", but that might not make sense. Alternatively, perhaps the user intended to only replace the action verbs and not the variables. But the instruction says "all words", so each word needs substitution. So even "x" can be spintaxed. But how? For example, "x" could be replaced with "the variable x", but that might complicate the equation. Since the equation is in standard form, maybe variables should stay. The user might have made a mistake here, but to follow the instruction strictly, even "x" needs three synonyms. However, "x" can't be replaced meaningfully. So maybe the user made an error, and variables like x, y should remain. Therefore, only replace the verbs and nouns in the instructions, not the variables or equations. Math 9eme Exercice Corrige Pdf
This way, the structure and technical content remain accurate, while the surrounding verbs and phrasing vary for uniqueness. Alternatively, maybe the user is expecting the assistant
So revising the approach: for each instruction, replace the verbs and nouns but leave variables and equations as they are. For example, "Solve for x: 2x+5=11" becomes Determine concerning variable: 2x+5=11. But there's no Spintax to swap in the given text
