-1/2+4-3/2

Solution

- \frac{1}{2} + 4 - \frac{3}{2}

2

Solution steps

- \frac{1}{2} + 4 - \frac{3}{2}

Follow the PEMDAS order of operations

Add and subtract (left to right)

- \frac{1}{2} + 4 = \frac{7}{2}

- \frac{1}{2} + 4

Convert element to fraction:

4 = \frac{4 \cdot 2}{2}

= \frac{4 \cdot 2}{2} - \frac{1}{2}

Since the denominators are equal, combine the fractions:

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

= \frac{4 \cdot 2 - 1}{2}

4 \cdot 2 - 1 = 7

4 \cdot 2 - 1

Multiply the numbers:

4 \cdot 2 = 8

= 8 - 1

Subtract the numbers:

8 - 1 = 7

= 7

= \frac{7}{2}

= \frac{7}{2} - \frac{3}{2}

\frac{7}{2} - \frac{3}{2} = 2

\frac{7}{2} - \frac{3}{2}

Apply rule

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

= \frac{7 - 3}{2}

Subtract the numbers:

7 - 3 = 4

= \frac{4}{2}

Divide the numbers:

\frac{4}{2} = 2

= 2

= 2

(4)^{3} - 48 (4)

\frac{1}{5} \times 5 \div \frac{1}{4}

(12 + 4)^{2} (1 + 1)

9 \div 3 + 4 \times 6

19 - (23 + 13 - 22)
