2^{2} - 4 (6) (3)

- 68

Solution steps

2^{2} - 4 (6) (3)

Follow the PEMDAS order of operations

Calculate exponents

2^{2} : 4

2^{2}

2^{2} = 4

= 4

= 4 - 4 (6) (3)

Multiply and divide (left to right)

4 (6) (3) : 72

4 (6) (3)

4 (6) = 24

4 (6)

Apply rule:

(a) = a

(6) = 6

= 4 \cdot 6

Multiply the numbers:

4 \cdot 6 = 24

= 24

= 24 (3)

24 (3) = 72

24 (3)

Apply rule:

(a) = a

(3) = 3

= 24 \cdot 3

Multiply the numbers:

24 \cdot 3 = 72

= 72

= 72

= 4 - 72

Add and subtract (left to right)

4 - 72 : - 68

4 - 72

4 - 72 = - 68

= - 68

= - 68

2 + 5 - 6 (4) \div 2 + 3

(10 - 7) - (- 2 - 6)

(10 - 11)^{2} + (100 - 10 \times 5)

2 5^{2} \cdot 3

- 3 - 2^{2}
