It depends on what you mean by "more or less". If more or less is used to indicate approximately or nearly equal to, then the symbol used is ≈ which look like a wriggly equals symbol. If more or less is used for more than or less than but not equal to, then you would use an equals sign with a diagonal line through it ≠ which stands for "not equal to" You are right but if it's more than or less than it would look like this (less than)<(more) or (more than)>
It looks like >
The symbol is: < Example: 8<12 is like saying: "8 is less than 12."
The "more than" symbol is the > symbol. The "less than" symbol is the < symbol.
The less than symbol looks like this: < This is where A < B ; A is less than B
The greater than symbol is > Example: -5 negative is greater than -10 negative -5 > -10
< The symbol for "less than" is <. For example: 4<6 This is essentially saying, "four is less than six."
56 < 90 greetaer than 56 > 90 less than
