GRE考试数学考点:Linear Equation of One Variable

Linear Equation of One Variable

An equation of one variable where the variable have unit power is called a linear equation(LE).

Example:

2x-3=8 and 3x-10=0 are both linear equations.

2x2=8 and 3x+√x=14 are not linear equations.

Remember:

In linear equation there is no square, square root, or other powers.

GRE考试数学考点:Mode

The mode of a set of numbers is the number that repeats the most in the set.

Example:

Mode of the set {1,2,3,2,4,5} is 2.

The set of numbers {1,2,4,1,2,3,6,8}has two modes:1 and 2.

Remember:

There can be more than one number with the highest repeat count. In that case all of them with the highest repeat count are modes.
