3*(-1/2)+1

Solution

3 \cdot (- \frac{1}{2}) + 1

- \frac{1}{2}

Solution steps

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

Follow the PEMDAS order of operations

Multiply and divide (left to right)

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

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

Apply rule

a \cdot (- b) = - a \cdot b

3 (- \frac{1}{2}) = - 3 \cdot \frac{1}{2}

Convert element to fraction:

3 = \frac{3}{1}

= - \frac{3}{1} \cdot \frac{1}{2}

Apply the fraction rule:

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

\frac{3}{1} \cdot \frac{1}{2} = \frac{3 \cdot 1}{1 \cdot 2}

= - \frac{3 \cdot 1}{1 \cdot 2}

Multiply the numbers:

3 \cdot 1 = 3

= - \frac{3}{1 \cdot 2}

Multiply the numbers:

1 \cdot 2 = 2

= - \frac{3}{2}

= - \frac{3}{2} + 1

Add and subtract (left to right)

- \frac{3}{2} + 1 : - \frac{1}{2}

- \frac{3}{2} + 1

- \frac{3}{2} + 1 = - \frac{1}{2}

- \frac{3}{2} + 1

Convert element to fraction:

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

= \frac{1 \cdot 2}{2} - \frac{3}{2}

Since the denominators are equal, combine the fractions:

\frac{a}{c} \pm \frac{b}{c} = \frac{a \pm b}{c}

= \frac{1 \cdot 2 - 3}{2}

1 \cdot 2 - 3 = - 1

1 \cdot 2 - 3

Multiply the numbers:

1 \cdot 2 = 2

= 2 - 3

Subtract the numbers:

2 - 3 = - 1

= - 1

= \frac{- 1}{2}

Apply the fraction rule:

\frac{- a}{b} = - \frac{a}{b}

= - \frac{1}{2}

= - \frac{1}{2}

= - \frac{1}{2}

1 \times (- 2) + 1

90 - (- 3) + (10) - (- 20)

(- 3) \cdot (- 20 + 7)

9 + [4 - (3 + 7 - 7) + (- 4 + 1)]

(- 11) (5 - 3) + (- 3 + 7)
