The first step is to choose a scale on the number line. Now, let us learn how to subtract integers on a number line. Any one of the given integers can be taken as the base point from where we start moving on the number line.Adding a negative integer will be done by moving towards the left side (or the negative side) of the number line.Adding a positive number will be done by moving towards the right side (or the positive side) of the number line.Every subtraction fact can be written as an addition fact.The subtraction of integers on a number line is based on the given principles: As 5 is the minuend here with a positive sign, so the answer sign will be positive. Now, find the sum of these absolute values which is 9 + 5 = 14. The absolute value of -9 is 9, and of 5 is 5. For example, if we want to subtract -9 from 5, first we find the absolute values of both. This can also be understood with another method in which we add the absolute values, and then attach the sign of the minuend with the result. For example, if we want to subtract -9 from 5, that is 5 - (-9), we will change the sign of 9 and then add the integers, which means it will be 5 + 9 = 14. Then, we need to check if both the integers become positive, the result will be positive and if both the integers are negative, then the result will be negative. Subtracting two integers with different signs is done by changing the sign of the integer that is subtracted. Subtracting Integers with Different Signs Some examples of subtracting integers with the same sign are given below: For example, 4 - 7 is the same as 4 + (-7). Here, it is important to note that every subtraction fact can be written as an addition fact. Since 5 > 2, the sign of the answer will be the same as the sign of 5, which is positive. Now, the absolute value of 5 is 5, and of -2 is 2. For example, -2 -(-5), can be written as -2 + 5. For subtraction of integers, we change the sign of the subtrahend. For an instance, the absolute value of 6 is 6, the absolute value of -6 is 6, etc. The absolute value of a number is the positive value of the given number. When we subtract two integers with the same sign, we subtract their absolute values and place the common sign in the result. The table given below shows the subtracting integer rules with examples. If both the numbers are of different signs, then we find the difference of the absolute numbers and place the sign of the bigger number in the result. After this step, if both numbers are of the same sign, then we add the absolute values and attach the common sign. Subtraction of integers is done by changing the sign of the subtrahend.If we subtract any integer from 0, we will find the additive inverse or the opposite of the integer.
