        evaluate means to calculate the amount or value of something, which in in this case is the algebraic expression.
        
        For example:
        
        The sum of 8 and y translates to 8 + y
        
        4 less than x translates to x – 4
        
        To be able to evaluate an algebraic expression, you need to substitute a
        number for each of the letters (variables) in an equation.

        -Scales on maps and drawings are often written as ratios.
        
        -You can then work out the distance between two places on a map or the actual size of something by using these scales.
        
        For example, if 1cm is equal to 75km, 3cm on the map would be equal to 225km.
        
        Ratios can also show the relationship between two groups.
        
        Examples :The ratio of frigates to aircraft carriers are 4 : 1 (four to one).
        The ratio of aircraft carriers to frigates are 1 : 4 (one to four).
