Subtraction of Integers
We will learn subtraction
of integers using number line.
We know that subtraction is the inverse of addition.
Therefore, to subtract an integer, we add its additive inverse.
For example, to
find +5 – (+2), we add +5 + (-2).
So, on the number line, we move to the left of +5 by 2 steps. +5 + (-2) = +3.
We know that to get a predecessor of a number we subtract 1.
So, predecessor of -20 is -20 - 1 = -21 and successor is -20 + 1 = -19
Solved examples on Subtraction of Integers:
1. Subtract +4 from +7.
+7 – (+4) = +7 + (-4). So, we move 4 steps left to 7 on the
Hence, +7 + (-4) = 3.
2. Subtract (-3) from (-7).
-7 – (-3) = -7 + (+3) = -4. So, we move 3 steps to the right of -7 on the number line.
Hence, (-3) from (-7) = -4.

In 5th Grade Integers Worksheet we will solve how to show the given integers on the number line, addition and subtraction of integers using number line, comparison of integers, absolute value of an integer, true or false statements of integers and word problems on integers.
Practice the questions given in the worksheet on addition and subtraction using number line. We know, adding a negative number means moving to the left-side on the number line and adding a positive number means moving to the right-side on the number line.
We will learn addition of integers using number line. We know that counting forward means addition. When we add positive integers, we move to the right on the number line. For example to add +2 and +4 we move 4 steps to the right of +2. Thus, +2 +4 = +6.
I. Compare the given numbers and put the right sign >, < or =. You may think of a number line when considering the answers:
When we represent integers on the number line, we observe that the value of the number increases as we move towards right and decreases as we move towards left. The whole numbers are on the right side of the 0 and in the left side of the 0 there are negative numbers.
Practice the questions given in the worksheet on absolute value of an integer. We know that, the absolute value of an integer is its numerical value without taking the sign into consideration. I. Write the absolute value of each of the following: (i) 15 (ii) -24 (iii) -375
Absolute value of an integer is its numerical value without taking the sign into consideration. The absolute values of -9 = 9; the absolute value of 5 = 5 and so on. The symbol used to denote the absolute value is, two vertical lines (| |), one on either side of an integer.
Practice the questions given in the worksheet on integers and the number line. The questions are based on integers and how to find the integers using a number line. I. Using the following number line, fill in the blanks:
What are integers? The negative numbers, zero and the natural numbers together are called integers. A collection of numbers which is written as... -4, -3, -2, -1, 0, 1, 2, 3, 4.. . These numbers
