Chess engines assess positions numerically. Chess Openings Wizard refers to engine evaluations as numeric assessments.
Numeric assessments are expressed in centipawns which means 100 points for the worth of a pawn. For example if the engine calculates that White is up a pawn, it will assess the position with a number around 100.
Similarly if Black is ahead, the engine will assess it with a negative number. Black up a pawn will have an assessment of around -100.
