Robert says that the expressions 2 + 3 x 7 and 2 + (3x7) have the same value. Is Robert correct? Explain your answer.

Robert is correct. The expression 2 + 3 x 7 has no grouping symbols, so 3 x 7 must be evaluated first by the order of operations. 2 + 21 = 23. The expression 2 + (3x7) has grouping symbols, so 3 x 7 must be evaluated first. This expression also has a value of 2 + 21=23. They have the same value.
