★★★★★ Sriram Venkataramani · Apr 23, 2021

Trinery is non utf, it can be used in schools and colleges for learning computational (computer math. This is because it uses 3-step multiplication, anf division as;3 x3 ot 3/3/3. In a cube of six sides the number to be multipled or divided is used by 3 succeeding sides and the answer is displayed in 3 steps by the othe 3 succeeding cubes.rubixcubixetc,
