What is the meaning of numbers during analysing the game?


+ means white has the advantage.
- means black has the advantage.
1.00 = 1 pawn.
.50 = half a pawn.
.33 = third of a pawn.

Of course @souptime4 is correct.
Just wanted to add something that may be confusing to new players. You don't need to have an extra pawn to be ahead 1.00 -- the numbers take into account positional factors too. So the material may be equal, but one side may be ahead 2.34 because their pieces are placed better, and/or king is safer, etc.

Hello, thank you for illustrating this matter. but I still dont get it. is there any article that explain this matter ? I have clue how even google it? how is it called ?

The numbers indicate which side the computer thinks is winning. If it is 0 then the computer then the computer thinks the game is level. If the number is +ve it thinks white is winning; if the number is -ve it thinks that black is winning. The bigger the number the more the side indicated is winning.
A score of about +/- 1 indicates that the difference between the two sides is about the difference of losing one pawn.

To find this I put 'numerical analysis of chess positions' into google.
