3\div 2-1

Solution

3 \div 2 - 1

\frac{1}{2}

Solution steps

3 \div 2 - 1

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} - 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

Add/Subtract the numbers:

- 2 + 3 = 1

= 1

= \frac{1}{2}

= \frac{1}{2}

= \frac{1}{2}

12 + 15 \times 3 - 10

\frac{( 2 ^{3} + 52 )}{2 ^{2}}

15 \times 1^{2} - 29 \times 1 - 12

74 + \frac{4}{16} - \frac{2}{23}

3 \cdot 10 + 3 \cdot 5^{2} + 3
