Which sentence explains why Lara and David found different values for the expressions? Laura dijo que el valor de [18 − (2 × 5)] + (30 × 2) es 68. David dijo que el valor de [ (18 − 2) × 5] + (30 × 2) es 140. ¿Cuál oración explica por qué Laura y David encontraron diferentes valores para las expresiones?

• Lara multiplied first, but she should have subtracted because the subtraction is before the multiplication.

• Both answers are correct because the grouping symbols change the order in which the operations are performed.

• David found the wrong answer because he did not pay attention to the parentheses and brackets.

• Both answers are incorrect because it is not possible to have 3 operations in the same expression.
