Answer 3

The expression "6÷2(1+2)" is ambiguous because it lacks explicit parentheses to indicate the order of operations. The ambiguity arises due to different interpretations of how to evaluate the expression.

Let's examine the two possible interpretations:

1. Ambiguous Interpretation: In this interpretation, the expression is evaluated from left to right, following standard order of operations (PEMDAS/BODMAS):

6 ÷ 2(1 + 2) = 6 ÷ 2 * (1 + 2) = 3 * (1 + 2) = 3 * 3 = 9

2. Assuming Implicit Parentheses: Another interpretation is that there are implicit parentheses around the "2(1+2)" term. This means the expression should be interpreted as follows:

6 ÷ 2(1 + 2) = 6 ÷ [2 * (1 + 2)] = 6 ÷ (2 * 3) = 6 ÷ 6 = 1

So, depending on the interpretation, the result of the expression can be either 9 or 1.

To avoid ambiguity and clearly convey your intentions, it's always best to use explicit parentheses to indicate the order of operations. For example, you could write the expression as:

6 ÷ 2 * (1 + 2) (to get 9) or 6 ÷ (2 * (1 + 2)) (to get 1)
