Follow the PEMDAS order of operations

Calculate exponents

(5)^{2} : 25

(5)^{2}

(5)^{2} = 25

= 25

= 3 \cdot 25 + 7 (5) + 2

Multiply and divide (left to right)

3 \cdot 25 : 75

3 \cdot 25

3 \cdot 25 = 75

= 75

= 75 + 7 (5) + 2

Multiply and divide (left to right)

7 (5) : 35

7 (5)

Apply rule:

(a) = a

(5) = 5

= 7 \cdot 5

Multiply the numbers:

7 \cdot 5 = 35

= 35

= 75 + 35 + 2

Add and subtract (left to right)

75 + 35 + 2 : 112

75 + 35 + 2

75 + 35 = 110

= 110 + 2

110 + 2 = 112

= 112

= 112

\frac{4}{5} - \frac{2}{6}

(8 - 6) - (3 - 7 - 2) + (1 - 8 + 2)

\frac{1 - 4 ( - 4 )}{15}

(3 \times 7 + 2 \times 15) \times (81 + 4 \times 20)

- 3 + 4 (- 2 (5))
