Primary Number Line

Introduction to primary number line:

The line is marked with the number is called primary number line. The number line has both positive and negative number. The center point of the primary number line is zero. The zero will not be neither positive nor negative. The positive may or may not have the positive sign on primary number line. But the negative numbers should have negative sign(“-“)

Example for Primary Number Line:

Example 1:

Point the expression x < 3 and x > -2 on the primary number line

Solution:

The expressions x < 3 and x > -2 can be written as -2
Example 2:

Point the expression n > -1 and n < 4on the primary number line

Solution:

The expressions n > -1 and n < 4on can be written as -1 < n < 4. This means, n is greater than -1 but less than 4. Please express your views of this topic second order differential equation by commenting on blog.
