2-5/2+3/2

Solution

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

1

Solution steps

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

Follow the PEMDAS order of operations

Add and subtract (left to right)

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

2 - \frac{5}{2}

Convert element to fraction:

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

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

2 \cdot 2 - 5 = - 1

2 \cdot 2 - 5

Multiply the numbers:

2 \cdot 2 = 4

= 4 - 5

Subtract the numbers:

4 - 5 = - 1

= - 1

= \frac{- 1}{2}

Apply the fraction rule:

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

= - \frac{1}{2}

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

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

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

Apply rule

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

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

Add/Subtract the numbers:

- 1 + 3 = 2

= \frac{2}{2}

Apply rule

\frac{a}{a} = 1

= 1

= 1

4 (- 4) + 3

3^{2} - 3^{0}

2 (3)^{2} - 4 (3) - 6

120 - (24 \div 4 + [25 + (2 \times 9) - 7 \times 4])

[5 - 2 (4 \times 5 \div 2) + 6]
