56

Solution steps

\frac{7}{2} \cdot 2^{4}

Follow the PEMDAS order of operations

Calculate exponents

2^{4} : 16

2^{4}

2^{4} = 16

= 16

= \frac{7}{2} \cdot 16

Multiply and divide (left to right)

\frac{7}{2} \cdot 16 : 56

\frac{7}{2} \cdot 16

Convert element to fraction:

16 = \frac{16}{1}

= \frac{7}{2} \cdot \frac{16}{1}

Apply the fraction rule:

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

= \frac{7 \cdot 16}{2 \cdot 1}

Cancel

\frac{7 \cdot 16}{2 \cdot 1} : 56

\frac{7 \cdot 16}{2 \cdot 1}

Multiply the numbers:

2 \cdot 1 = 2

= \frac{7 \cdot 16}{2}

Divide the numbers:

\frac{16}{2} = 8

= 7 \cdot 8

Multiply the numbers:

7 \cdot 8 = 56

= 56

= 56

= 56

3 \times 6^{2}

6^{2} - 8

5 + 3 (5 - 7)

25 - (15 + 1 \cdot 6)

15 - (- 4) - (- 2 + 27)
