Camau Ateb

Tynnu 37 o 24 i gael -13.

$$sort(-13-\left(-31\right),-11-\left(-8\right)-\left(-5\right)-17)$$

Gwrthwyneb -31 yw 31.

$$sort(-13+31,-11-\left(-8\right)-\left(-5\right)-17)$$

Adio -13 a 31 i gael 18.

$$sort(18,-11-\left(-8\right)-\left(-5\right)-17)$$

Gwrthwyneb -8 yw 8.

$$sort(18,-11+8-\left(-5\right)-17)$$

Adio -11 a 8 i gael -3.

$$sort(18,-3-\left(-5\right)-17)$$

Gwrthwyneb -5 yw 5.

$$sort(18,-3+5-17)$$

Adio -3 a 5 i gael 2.

$$sort(18,2-17)$$

Tynnu 17 o 2 i gael -15.

$$sort(18,-15)$$
