Integers on number lines
key notes :
In Maths, number lines are the horizontal straight lines in which the integers are placed in equal intervals. All the numbers in a sequence can be represented in a number line. This line extends indefinitely at both ends.
Every real number is represented by a unique point on the Number line. Also, every point on a number line represents one & only one Real number. We use the process of successive magnification to represent a number on number line.
Integers on number lines
You can plot integers on number lines. On a number line, negative integers are to the left of zero, and positive integers are to the right of zero.
Let’s try it. Plot 2 on the integer number line. The integer 2 is positive, so it is to the right of zero.
Let’s try it for another example. Plot –4 on the integer number line. The integer –4 is negative, so it is to the left of zero.
Learn with an example
▶️ Type the missing number.
- Each interval represents 1, so find the missing number by adding or subtracting 1.
- The missing number is larger than –1, so add 1. Since –1 + 1 = 0, the missing number is 0.
▶️ Type the missing number.
- Each interval represents 1, so find the missing number by adding or subtracting 1.
- The missing number is larger than 4, so add 1. Since 4 + 1 = 5, the missing number is 5.
▶️ Type the missing number.
- Each interval represents 1, so find the missing number by adding or subtracting 1.
- The missing number is larger than –54, so add 1. Since –54 + 1 = –53, the missing number is –53.
