Translating verbal language to the language of mathematics, that is solving a word problem, involves three stages: (i) encoding, (ii) operations, (iii) decoding. Which one of the following examples best describes the encoding process?
1
Suppose we say that "a father's age is 5 years more than twice his son's age". If we assume the two ages to be x and y years respectively, then the corresponding mathematical model is X = 2Y + 5
2
After a model has been set up, we operate on it according to given conditions, obtain a solution and then translate it back into verbal language.
3
The process of proving the sum of the three angles of a triangle is two right angles. Here, the hypothesis is "a triangle" and the knowledge of results related to angles such as alternate angles.
