The following claims were verified through Perplexity Sonar before the questions were finalised. The host can reference any of them during play:

• Algebra is the branch of mathematics that uses alphabetical letters, called variables, to represent unknown numbers.
• A variable is a symbol, usually a letter like x or y, that represents a number we do not know yet.
• A constant is a fixed number on its own that does not contain a variable.
• A coefficient is the number used to multiply a variable, such as 4 in the term 4x.
• When a variable appears without a number next to it, like x, it has a coefficient of 1.
• An algebraic expression is a group of terms separated by plus or minus signs, such as 5x + 6.
• An equation is a statement that says two things are equal and always includes an equals sign.
• The word 'Algebra' comes from the Arabic word 'al-jabr,' which loosely translates to balancing and restoring.
• The four basic rules of algebra are the commutative and associative rules for addition and multiplication.
• Like terms are terms that have the same variable and the same exponent, allowing them to be combined.
• The order of operations in algebra is determined by the PEMDAS or BODMAS rule.
• Polynomials can include constants, variables, and exponents 0, 1, 2, 3, but never division by a variable.
