-3-5(1/2)

Solution

- 3 - 5 (\frac{1}{2})

- \frac{11}{2}

Solution steps

- 3 - 5 (\frac{1}{2})

Follow the PEMDAS order of operations

Multiply and divide (left to right)

5 (\frac{1}{2}) : \frac{5}{2}

5 (\frac{1}{2})

Apply rule:

(a) = a

(\frac{1}{2}) = \frac{1}{2}

= 5 \cdot \frac{1}{2}

5 \cdot \frac{1}{2} = \frac{5}{2}

5 \cdot \frac{1}{2}

Convert element to fraction:

5 = \frac{5}{1}

= \frac{5}{1} \cdot \frac{1}{2}

Apply the fraction rule:

\frac{a}{b} \cdot \frac{c}{d} = \frac{a \cdot c}{b \cdot d}

= \frac{5 \cdot 1}{1 \cdot 2}

Multiply the numbers:

5 \cdot 1 = 5

= \frac{5}{1 \cdot 2}

Multiply the numbers:

1 \cdot 2 = 2

= \frac{5}{2}

= \frac{5}{2}

= - 3 - \frac{5}{2}

Add and subtract (left to right)

- 3 - \frac{5}{2} : - \frac{11}{2}

- 3 - \frac{5}{2}

- 3 - \frac{5}{2} = - \frac{11}{2}

= - \frac{11}{2}

= - \frac{11}{2}

7 [3 + 4 (2 - 5)]

- 1 + 5 - 9 - 15
