354/5+2*5^2

3 \cdot 5 \cdot \frac{4}{5} + 2 \cdot 5^{2}

62

Solution steps

3 \cdot 5 \cdot \frac{4}{5} + 2 \cdot 5^{2}

Follow the PEMDAS order of operations

Calculate exponents

5^{2} : 25

5^{2}

5^{2} = 25

= 25

= 3 \cdot 5 \cdot \frac{4}{5} + 2 \cdot 25

Multiply and divide (left to right)

3 \cdot 5 \cdot \frac{4}{5} : 12

3 \cdot 5 \cdot \frac{4}{5}

3 \cdot 5 = 15

= 15 \cdot \frac{4}{5}

15 \cdot \frac{4}{5} = 12

15 \cdot \frac{4}{5}

Convert element to fraction:

15 = \frac{15}{1}

= \frac{15}{1} \cdot \frac{4}{5}

Apply the fraction rule:

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

= \frac{15 \cdot 4}{1 \cdot 5}

Cancel

\frac{15 \cdot 4}{1 \cdot 5} : 12

\frac{15 \cdot 4}{1 \cdot 5}

Multiply the numbers:

1 \cdot 5 = 5

= \frac{15 \cdot 4}{5}

Divide the numbers:

\frac{15}{5} = 3

= 3 \cdot 4

Multiply the numbers:

3 \cdot 4 = 12

= 12

= 12

= 12

= 12 + 2 \cdot 25

Multiply and divide (left to right)

2 \cdot 25 : 50

2 \cdot 25

2 \cdot 25 = 50

= 50

= 12 + 50

Add and subtract (left to right)

12 + 50 : 62

12 + 50

12 + 50 = 62

= 62

= 62

(- 7) + 12 + 6 + (- 5) + (- 3) + 7

5^{2} \times 6^{2}

\frac{1}{2} + 6 (1 + \frac{1}{2})

(2)^{2} - 5 (2) + 1

36 + 20 - 5 - 62 + 9
