During your presentation, you mentioned that a student^s response of ^12 buah^ (12
fruits) to the sum of eight oranges and four bananas problem was interpreted as
incorrect due to the use of different variables for oranges and bananas. However,
wouldn^t it be more appropriate to consider the problem in a straightforward arithmetic
context, where the number of oranges is 8, and the number of bananas is 4? In such a
context, the student^s answer ^12 fruits^ would be considered correct. I^d like to
understand the reasoning behind the interpretation and whether the introduction of
variables is necessary for this specific problem.
sorry in advance, in my opinion the variable should be clear, is it an orange or is it a banana. for example x = number of oranges and y = number of bananas, is it 4x+8y = 12xy? In my opinion, the introduction of variables from the start is very important so that you don^t experience subsequent errors, sorry if my answer is not quite right
