4^2-(-5)^2-(-2)\times (3)

4^{2} - (- 5)^{2} - (- 2) \cdot (3)

- 3

Solution steps

4^{2} - (- 5)^{2} - (- 2) (3)

Follow the PEMDAS order of operations

Calculate exponents

4^{2} : 16

4^{2}

4^{2} = 16

= 16

= 16 - (- 5)^{2} - (- 2) (3)

Calculate exponents

(- 5)^{2} : 25

(- 5)^{2}

Apply exponent rule:

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

n

is even

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

= 25

= 16 - 25 - (- 2) (3)

Multiply and divide (left to right)

(- 2) (3) : - 6

(- 2) (3)

Apply rule

(- a) \cdot (b) = - a \cdot b

(- 2) (3) = - 2 \cdot 3 = - 6

= - 6

= 16 - 25 - (- 6)

Add and subtract (left to right)

16 - 25 - (- 6) : - 3

16 - 25 - (- 6)

16 - 25 = - 9

= - 9 - (- 6)

Apply rule

- (- a) = + a

- (- 6) = + 6

= - 9 + 6

- 9 + 6 = - 3

= - 3

= - 3

(- 1 + 1)^{2} - 3

3/5 \cdot 3/4

3 (\times (- 3)) 1 \times (- 4)

(129 - 32) - (87 + 16) + (47 - 31) - (17 + 19) + (50 - 25)

6^{2} + (- 1^{2})
