(30)^{2}

(30)^{2} = 900

= 900

= 9 \cdot 900 - 4 (30) + 12

Multiply and divide (left to right)

9 \cdot 900 : 8100

9 \cdot 900

9 \cdot 900 = 8100

= 8100

= 8100 - 4 (30) + 12

Multiply and divide (left to right)

4 (30) : 120

4 (30)

Apply rule:

(a) = a

(30) = 30

= 4 \cdot 30

Multiply the numbers:

4 \cdot 30 = 120

= 120

= 8100 - 120 + 12

Add and subtract (left to right)

8100 - 120 + 12 : 7992

8100 - 120 = 7980

= 7980 + 12

7980 + 12 = 7992

= 7992

= 7992
