Praxis 5511 Practice Test Practice Question
Mr. Sanchez asks his fifth-grade mathematics students to solve the word problem above by finding the value of the expression $25-4+12$. Which of the following topics of mathematics is Mr. Sanchez illustrating?
Correct Answer: A
Rationale: Mr. Sanchez's problem requires students to evaluate the expression \(25 - 4 + 12\). This involves applying the rules of order of operations, which dictate that addition and subtraction are performed from left to right.
Option B is incorrect as it refers to solving systems of linear equations, which is not relevant here. Option C incorrectly identifies the associative property, which pertains to grouping in addition (e.g., \((a + b) + c = a + (b + c)\)), not applicable in this context. Option D misapplies the distributive property, which involves multiplying a number by a sum (e.g., \(a(b + c) = ab + ac\)), not relevant to the expression given.
