Number sem awlsam hriat dan:-

1. 2 in a sem theih number-te:- 2 in a sem theih number-te chu a tawp berah 0 emaw even number a awm thin.

2. 3 in a sem theih number-te:-3 in a sem theih number-te chu a number mal tin belhkhawm kha 3 in a sem thei tur a ni.

3.. 4 in a sem theih number-te-4 in a sem theih number-te chu a number tawp ber pahnihte kha 4 in a sem theihin emaw 0(zero) an nih in.

4. 5 in a sem theih number-te: Number hrim hrim a tawp ber number kha 5 emaw 0 a nihin 5 in a sem thei.

5. 6 in a sem theih number-te:- Number hrim hrim 2 leh 3 in a sem kawp theih chuan 6 in a sem thei.

6. 7 in a sem theih number-te-7 in a sem theih number-te hriat theih dan chu a number mal tawp ber kha 2 a pun tirin chu chu a number dangte atangin kan paih ang a, mumber thar kan hmuh chhuah chu 7 in a sem thei thin. Entirnan, 658 hi 7 in a sem thei em?

65-2×8-65-16-49, 49 hi 7 in a sem thei a, chu vangin 658 hi 7 in a sem thei.

7. 8 in a sem theih number-te-8 in a sem theih number-te chu a number tawp ber pathum te kha 8 in a sem theihin emaw 0(zero) an nih in.

8. 9 in a sem theih number-te:-9 in a sem theih number-te chu a number mal tin belhkhawm kha 9 in a sem thei tur a ni.

9. 10 in a sem theih number-te: Number hrim hrim a tawp ber number kha 0 a nihin  phawt chuan10 in a sem thei.

10.11 in a sem theih number-te:-11 in a sem theih number-te chu a number inkar thlaka kan belh khawm ve ve a intluk chiahin emaw an danglamna kha 11 in a sem theihin.

11. 12 in a sem theih number-te: Number hrim hrim 4 leh 3 in a sem kawp theih chuan 12 in a sem thei

12.. 13 in a sem theih number-te: 13 in a sem theih number-te hriat theih dan chu a number mal tawp ber kha 4 a pun tirin chu chu a number dangte nen belh tur a ni a number thar hmuh chhuah chu 13 in a sem thei thin. Entirman, 247 hi 13 in a sem thei, a chhan chu 24 + 7 x 4 = 52, 52 hi 13 a sem theih vang a ni.
