1. To calculate $6/3+4-1$:
1. Parentheses and fraction bars: There are none in this example.
2. Exponents: There are none in this example.
3. Multiplication and division: Do the single division $6/3$:
$\color{indianred}{6/3} + 4 - 1 = 2 + 4-1$.
4. Addition and subtraction: Do the remaining additions and subtractions from left to right:
$\color{indianred}{2+4} - 1 = 6 - 1 = 5$.

2. To calculate $6/(4-6) \times 2 -2^3$:
1. Parentheses and fraction bars: First calculate the value of the entire quantity in parentheses (using the the order of operations as necessary).
$\color{indianred}{6/(4-6)} \times 2 -2^3 = 6/(-2) \times 2 -2^3$.
2. Exponents: Raise all numbers to the indicated powers.
$6/(-2) \times 2 -\color{indianred}{2^3} = 6/(-2) \times 2 - 8$.
3. Multiplication and division: Do all the multiplications and divisions from left to right:
$\color{indianred}{6/(-2)} \times 2 - 8 =\color{indianred}{-3 \times 2} - 8 = -6 - 8$.
4. Addition and subtraction: Do the remaining additions and subtractions from left to right:
$\color{indianred}{-6 - 8} = -14$.
Some for you
