no, to add and subtract like and unlike fractions the denominator has to be the same,
You have to convert them to equivalent similar fractions (fractions with the same denominator) first.
In fractions, you can NEVER add or subtract
Because you can't add or subtract fractions that have different denominators. Making them like fractions, by multiplying so the denominators are the same, you can add and/or subtract them.

What is the answer for 8 1/3 - 5 2/6
You first convert them to similar fractions, i.e., to fractions that have the same denominator.* Step one: find a common denominator.* Step two: convert both fractions to equivalent fractions that have that denominator.
it stay the same when you subtract fractions and when you add fractions.
You need a common denominator in order to add or subtract fractions.
I assume you mean, with different denominators. If you want to add the fractions, subtract them, or compare them (determine which one is greater), you have to convert them to similar fractions (fractions with the same denominator) first. Converting to similar fractions is not necessary, and usually doesn't even help, if you want to multiply or divide fractions.

Dissimilar fractions are fractions that have different denominators.
