14

Solution steps

0 - (- 21) \frac{2}{3}

Follow the PEMDAS order of operations

Multiply and divide (left to right)

(- 21) \frac{2}{3} : - 14

(- 21) \frac{2}{3}

Apply rule

(- a) \cdot b = - a \cdot b

(- 21) \frac{2}{3} = - 21 \cdot \frac{2}{3}

Convert element to fraction:

21 = \frac{21}{1}

= - \frac{21}{1} \cdot \frac{2}{3}

Apply the fraction rule:

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

\frac{21}{1} \cdot \frac{2}{3} = \frac{21 \cdot 2}{1 \cdot 3}

= - \frac{21 \cdot 2}{1 \cdot 3}

Cancel

\frac{21 \cdot 2}{1 \cdot 3} : 14

\frac{21 \cdot 2}{1 \cdot 3}

Multiply the numbers:

1 \cdot 3 = 3

= \frac{21 \cdot 2}{3}

Divide the numbers:

\frac{21}{3} = 7

= 7 \cdot 2

Multiply the numbers:

7 \cdot 2 = 14

= 14

= - 14

= 0 - (- 14)

Add and subtract (left to right)

0 - (- 14) : 14

0 - (- 14)

Apply rule

- (- a) = + a

- (- 14) = + 14

= 0 + 14

0 + 14 = 14

= 14

= 14

- 30 + 10 - 5 + 7 - 15
