These symbols (or at least some of them) are related to general math/algebra.

Symbols:

&& : - This means and, in terms of PAWN, you could do 2 functions in 1 if statement. Example is below.

pawn Код:

if(IsPlayerConnected(playerid) && IsPlayerAdmin(playerid))

& : This I do not really know yet, but I do know a way you could use it. Example is below.

pawn Код:

if(newkeys & KEY_FIRE)

< : Less then, 1 < 5 - 1 is less then 5.

pawn Код:

if(PlayerInfo[playerid][Money] < GetPlayerMoney(playerid)) - //If their money is less then their client side money.

<< : I do not know yet.

>> : I do not know yet.

> : Greater then, 5 > 1 - 5 is greater then 1.

pawn Код:

if(GetPlayerMoney(playerid) > PlayerInfo[playerid][Money]) - //If their client side money is larger then their var money.

| : I do not know yet.

|| : This is like &&, but this is "or". You can use this for many things, such as strcmp.

pawn Код:

if(!strcmp(cmd, "/help", true) || !strcmp(cmd, "/h", true)) - //Comparing if they used /h or /help.

* : This is a math symbol, multiplication.

pawn Код:

75 * 3 - //Same thing as 75 x 3

- : This is a math symbol, subtraction. But this is used inside a function.

pawn Код:

300.0 - 250.0

-- : This is used to downgrade or subtract a variable.

pawn Код:

CountDown--;

= : This is a math symbol, basically equal to. It is used to assign a value to a var or array, etc.

pawn Код:

new Float:Health = 3000.0

== : This is a math symbol, similar to the equal sign, but instead, this is used to compare two functions/vars/arrays/etc.

pawn Код:

if(playerid == INVALID_PLAYER_ID) // This is used in a PM cmd, to see if they typed a invalid playerid.

+ : This is like subtraction, except, it is addition, you use it inside a function, to add numbers or variables/values.

pawn Код:

50.0 + 300.0

++ : This is like the subtraction sign for vars, but this is addition.

pawn Код:

CountDown++; //Will count upwards.

% : This is used to format a specifier, inside a format.

pawn Код:

%d - Whole Intenger | %s - string | %f - Float | %c - Single Character and more (search wiki)

>= : This is using the greater then, but also like assigning a var. This can be used to see a player's admin level in a if statement.

pawn Код:

if(PlayerInfo[playerid][pAdmin] >= 4) // This will check if the person's level is 4 or higher.

<= : This is using the less then, but also like assigning a var. This can be used to see a player's admin level in a if statement.

pawn Код:

if(PlayerInfo[playerid][pAdmin] <= 4) // This will check if the person's level is 4 or lower.

-= : This is like the subtraction sign, except used for vars/arrays/enums etc.

pawn Код:

PlayerInfo[playerid][Money] -= amount;

+= : This is like the addition sign, except used for vars/arrays/enums etc.

pawn Код:

PlayerInfo[palyerid][Money] += amount;

Hope this helped.
