What map displays our 3-dimension earth on a 2 dimensional surface

All maps tend to do that. Google Maps and OpenStreetMaps, like most Web maps, uses Web Mercater. This projection is unique as even when the world is laid out as a rectangle, the distance between two places on the map can be used to find the distance in real life. Other projections include the spherical Mercater and WGS84.

Amath expression is a collection of one or more terms, which are separated by the signs ( + , - , x , / ).example :   8+b8+b  or  a−3a−3in algebra, an equation is a mathematical statement with two expressions where, each expression is separated by an equal (=) sign. variables can be present on both the sides of the equality (=) sign and we use letters to denote such variables.example 1:   x=4+2x=4+2  , [here, we can observe that the variable is present only on one side of the equation].example 2:   2x+3=x+42x+3=x+4  , [here, we can observe that the variables are present on both side of the equation].
