Mga Hakbang ng Solution

Kalkulahin ang 10 sa power ng 18 at kunin ang 1000000000000000000.

$$2\times 1000000000000000000-4\times 10^{18}$$

I-multiply ang 2 at 1000000000000000000 para makuha ang 2000000000000000000.

$$2000000000000000000-4\times 10^{18}$$

Kalkulahin ang 10 sa power ng 18 at kunin ang 1000000000000000000.

$$2000000000000000000-4\times 1000000000000000000$$

I-multiply ang 4 at 1000000000000000000 para makuha ang 4000000000000000000.

$$2000000000000000000-4000000000000000000$$

I-subtract ang 4000000000000000000 mula sa 2000000000000000000 para makuha ang -2000000000000000000.
