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

Follow the PEMDAS order of operations

Calculate exponents

5^{2} : 25

5^{2}

5^{2} = 25

= 25

= 25 + 2 (5) - 4

Multiply and divide (left to right)

2 (5) : 10

2 (5)

Apply rule:

(a) = a

(5) = 5

= 2 \cdot 5

Multiply the numbers:

2 \cdot 5 = 10

= 10

= 25 + 10 - 4

Add and subtract (left to right)

25 + 10 - 4 : 31

25 + 10 - 4

25 + 10 = 35

= 35 - 4

35 - 4 = 31

= 31

= 31

16 \div 12 \cdot 8

(5 - 2)^{4}

(- 8) \times (- 3) \times (- 2)

2^{2} - 5 (2) + 6

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