-1*1/2+1

Solution

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

\frac{1}{2}

Solution steps

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

Follow the PEMDAS order of operations

Multiply and divide (left to right)

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

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

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

= - \frac{1}{2}

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

Add and subtract (left to right)

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

- \frac{1}{2} + 1

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

- \frac{1}{2} + 1

Convert element to fraction:

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

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

1 \cdot 2 - 1 = 1

1 \cdot 2 - 1

Multiply the numbers:

1 \cdot 2 = 2

= 2 - 1

Subtract the numbers:

2 - 1 = 1

= 1

= \frac{1}{2}

= \frac{1}{2}

= \frac{1}{2}

(- 15) + (- 25) + 18 + 25

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

\frac{3 ( 4 - 9 ) ^{2} + [ 6 - ( - 5 + 1 ) ]}{( 3 + 2 )}

10 \cdot 1 0^{0}

2 (2)^{2} - 3 (2) + 5
