256

Solution steps

30 (10) - \frac{11}{2} (8)

Follow the PEMDAS order of operations

Multiply and divide (left to right)

30 (10) : 300

30 (10)

Apply rule:

(a) = a

(10) = 10

= 30 \cdot 10

Multiply the numbers:

30 \cdot 10 = 300

= 300

= 300 - \frac{11}{2} (8)

Multiply and divide (left to right)

\frac{11}{2} (8) : 44

\frac{11}{2} (8)

Apply rule:

(a) = a

(8) = 8

= \frac{11}{2} \cdot 8

\frac{11}{2} \cdot 8 = 44

\frac{11}{2} \cdot 8

Convert element to fraction:

8 = \frac{8}{1}

= \frac{11}{2} \cdot \frac{8}{1}

Apply the fraction rule:

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

= \frac{11 \cdot 8}{2 \cdot 1}

Cancel

\frac{11 \cdot 8}{2 \cdot 1} : 44

\frac{11 \cdot 8}{2 \cdot 1}

Multiply the numbers:

2 \cdot 1 = 2

= \frac{11 \cdot 8}{2}

Divide the numbers:

\frac{8}{2} = 4

= 11 \cdot 4

Multiply the numbers:

11 \cdot 4 = 44

= 44

= 44

= 44

= 300 - 44

Add and subtract (left to right)

300 - 44 : 256

300 - 44

300 - 44 = 256

= 256

= 256

24 - 9 \cdot 2 + 6 \div 3

(9 - 2) 180

- 4 + 6 + (- 1)

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

2 + 2 \cdot 2
