3\div 2-2

Solution

3 \div 2 - 2

- \frac{1}{2}

Solution steps

3 \div 2 - 2

Follow the PEMDAS order of operations

Multiply and divide (left to right)

3 \div 2 : \frac{3}{2}

3 \div 2

3 \div 2 = \frac{3}{2}

= \frac{3}{2}

= \frac{3}{2} - 2

Add and subtract (left to right)

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

\frac{3}{2} - 2

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

\frac{3}{2} - 2

Convert element to fraction:

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

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

- 2 \cdot 2 + 3 = - 1

- 2 \cdot 2 + 3

Multiply the numbers:

2 \cdot 2 = 4

= - 4 + 3

Add/Subtract the numbers:

- 4 + 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}

49 - 45 \div 5 + 4

3 - 2 (- 4)

6 - 4 (1)

(- 8)^{2} + (- 6)^{2}

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