do equation must have a equal sign
Hi Kimderano,
< and > are inequality signs.
When you use these you have inequalities NOT equations.
dont know LOL
YES equations must have an equal sign
No, it can be x>5 (x is bigger than 5),x≤5 (x is smaller or is equal as 5),x≥5 (x is bigger or equal as 5),x≺5 (x is smaller than 5) or x=5 (x is equal as 5).
( and maybe more but i don't know about it)
