Solution steps

15 (2)^{4} - 4 (2)^{3}

Follow the PEMDAS order of operations

Calculate exponents

(2)^{4} : 16

(2)^{4}

(2)^{4} = 16

= 16

= 15 \cdot 16 - 4 (2)^{3}

Calculate exponents

(2)^{3} : 8

(2)^{3}

(2)^{3} = 8

= 8

= 15 \cdot 16 - 4 \cdot 8

Multiply and divide (left to right)

15 \cdot 16 : 240

15 \cdot 16

15 \cdot 16 = 240

= 240

= 240 - 4 \cdot 8

Multiply and divide (left to right)

4 \cdot 8 : 32

4 \cdot 8

4 \cdot 8 = 32

= 32

= 240 - 32

Add and subtract (left to right)

240 - 32 : 208

240 - 32

240 - 32 = 208

= 208

= 208

2 (3 + 1)

20 + (3 \times 4 - (17 - 3 \times 2^{2}) \times 2)

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

(3^{2} - 2^{2})^{3} + 42 \div 6 \times 3^{2} - 9

(- 3)^{2} + 6 (- 3) + 8
