15-32\times 5/9

15 - 32 \cdot \frac{5}{9}

- \frac{25}{9}

Solution steps

15 - 32 \cdot \frac{5}{9}

Follow the PEMDAS order of operations

Multiply and divide (left to right)

32 \cdot \frac{5}{9} : \frac{160}{9}

32 \cdot \frac{5}{9}

Convert element to fraction:

32 = \frac{32}{1}

= \frac{32}{1} \cdot \frac{5}{9}

Apply the fraction rule:

\frac{a}{b} \cdot \frac{c}{d} = \frac{a \cdot c}{b \cdot d}

= \frac{32 \cdot 5}{1 \cdot 9}

Multiply the numbers:

32 \cdot 5 = 160

= \frac{160}{1 \cdot 9}

Multiply the numbers:

1 \cdot 9 = 9

= \frac{160}{9}

= 15 - \frac{160}{9}

Add and subtract (left to right)

15 - \frac{160}{9} : - \frac{25}{9}

15 - \frac{160}{9}

15 - \frac{160}{9} = - \frac{25}{9}

15 - \frac{160}{9}

Convert element to fraction:

15 = \frac{15 \cdot 9}{9}

= \frac{15 \cdot 9}{9} - \frac{160}{9}

Since the denominators are equal, combine the fractions:

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

= \frac{15 \cdot 9 - 160}{9}

15 \cdot 9 - 160 = - 25

15 \cdot 9 - 160

Multiply the numbers:

15 \cdot 9 = 135

= 135 - 160

Subtract the numbers:

135 - 160 = - 25

= - 25

= \frac{- 25}{9}

Apply the fraction rule:

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

= - \frac{25}{9}

= - \frac{25}{9}

= - \frac{25}{9}

- (- 3)^{2} - 9 (- 3) + 3

- 1 - 3 \times (- 1) - 4

4 (- 1) + 1

(1 + 1) \times (\frac{1}{2} + 0)

4 [(32 - 5^{2}) - (2^{3} - 1)]
