Question
Use a checking method for this problem: final-answer check: simplify 24y + 25y by collecting like terms. State the final answer and verify it against the information in the question.
Answer
A valid checked answer is 49y. The method is: Start with 24y + 25y. The terms are like terms because both contain y. Add the coefficients 24 and 25. 49y The final line agrees with the canonical answer.
Explanation
calculator check keeps the canonical answer 49y fixed before the model answer is written, so the worked solution and final answer agree.
Common mistake
Algebraic vocabulary common mistake 1
Writing a final answer without showing the method that justifies it. This can weaken answers for: [Foundation and Higher] Understand and use algebraic vocabulary for expressions, equations, formulae, inequalities, terms and factors..
Show the method first, then give the final answer in the required form. Apply this directly to Algebraic vocabulary.
