Final answer:
Calculations with parentheses come first and calculations with exponents come last in the order of operations.
Step-by-step explanation:
In the order of operations, calculations with parentheses come first, followed by calculations with exponents, then multiplication and division, and finally addition and subtraction.
For example, in the expression 2 + 3 × (4 − 1)^2 ÷ 5, we would first perform the calculations in the parentheses (4 − 1 = 3) and the exponent (3^2 = 9). Then, we would perform the multiplication (3 × 9 = 27) and the division (27 ÷ 5 ≈ 5.4). Finally, we would perform the addition (2 + 5.4 ≈ 7.4).
