$$21160000+\left(4200-4800\right)^{2}+\left(2000\times 0.2-4800\right)^{2}$$

Naqqas 4800 minn 4200 biex tikseb -600.

$$21160000+\left(-600\right)^{2}+\left(2000\times 0.2-4800\right)^{2}$$

Ikkalkula -600 bil-power ta' 2 u tikseb 360000.

$$21160000+360000+\left(2000\times 0.2-4800\right)^{2}$$

Żid 21160000 u 360000 biex tikseb 21520000.

$$21520000+\left(2000\times 0.2-4800\right)^{2}$$

Immultiplika 2000 u 0.2 biex tikseb 400.

$$21520000+\left(400-4800\right)^{2}$$

Naqqas 4800 minn 400 biex tikseb -4400.

$$21520000+\left(-4400\right)^{2}$$

Ikkalkula -4400 bil-power ta' 2 u tikseb 19360000.

$$21520000+19360000$$

Żid 21520000 u 19360000 biex tikseb 40880000.
