3.3 Order of Operations

Calculate $21 - 4 \times 13$.

Calculate $4 \times 8^{3}$.

Calculate $2 + 3^{2} \times 4$.

Correctly apply the order of operations to compute the following:

$4 - 25 \times 6 / 10 \times 3^{2} + 7 \times 2^{3}$.

Correctly apply the rules for the order of operations to accurately compute the following:

$10 - 3 \times 5^{3} / 15 + 56 / 4$.

Correctly apply the rules for the order of operations to accurately compute the following: $\left(- 8\right) / 2 \times 3 - 9 \times 2^{4} / 12 + 9 \times \left(- 4\right)^{2} / 2^{3}$.

Correctly apply the rules for the order of operations to accurately compute the following:

$\left(10 - 3\right) \times 5^{3}$.

Correctly apply the rules for order of operations to accurately compute the following:

$4 + 2 \times \left(3^{2} - \left(2 + 5\right)^{2} \times 4\right) / \left(3 + 8\right)$.
