245\div 5-4+2(7-12)^2-5^2

245 \div 5 - 4 + 2 (7 - 12)^{2} - 5^{2}

70

Solution steps

245 \div 5 - 4 + 2 (7 - 12)^{2} - 5^{2}

Follow the PEMDAS order of operations

Calculate within parentheses

(7 - 12) : - 5

7 - 12

7 - 12 = - 5

= - 5

= 245 \div 5 - 4 + 2 (- 5)^{2} - 5^{2}

Calculate exponents

(- 5)^{2} : 25

(- 5)^{2}

Apply exponent rule:

(- a)^{n} = a^{n},

n

is even

(- 5)^{2} = 5^{2} = 25

= 25

= 245 \div 5 - 4 + 2 \cdot 25 - 5^{2}

Calculate exponents

5^{2} : 25

5^{2}

5^{2} = 25

= 25

= 245 \div 5 - 4 + 2 \cdot 25 - 25

Multiply and divide (left to right)

245 \div 5 : 49

245 \div 5

245 \div 5 = 49

= 49

= 49 - 4 + 2 \cdot 25 - 25

Multiply and divide (left to right)

2 \cdot 25 : 50

2 \cdot 25

2 \cdot 25 = 50

= 50

= 49 - 4 + 50 - 25

Add and subtract (left to right)

49 - 4 + 50 - 25 : 70

49 - 4 + 50 - 25

49 - 4 = 45

= 45 + 50 - 25

45 + 50 = 95

= 95 - 25

95 - 25 = 70

= 70

= 70

16 \div 2^{3} \times 3 - 4 \div 2

(25 + 5) - 18 + (8 \times 5)

- (- 4 + 18 \div 3) - 26

\frac{2}{3} (\frac{1}{5} + \frac{3}{4})

35 - 2 - 2 - 2
