While solving problems with large integers, don't always rely on the number line. Using integer arithmetic we can solve the problem of large integer. We need a rule for subtracting integers and the rule is:

Rule: To subtract an integer, add its opposite.

There are two basic rules for subtracting integers. If the integer you're subtracting is positive, then you decrease the value of the integer that it's being subtracted from by that amount. For example, 8 - 3 = 5 and 3 - 8 = -5. If the integer you're subtracting is negative, then you increase the value of the integer that it's being subtracted from by that amount. For example, 8 - (-3) = 11 and 3 - (-8) = 11 as well.

I would think that the commonality of adding and subtracting integers is that the answer itself will always be an integer. In other words, the answer is always gonna be a "whole number".




By regrouping the integer. If you were subtracting 3/8 from 7, you could rewrite 7 as 6 and 8/8. Subtract 3/8 and the answer is 6 and 5/8.

Rule: The sum of two negative integers is a negative integer.Rule: The sum of two positive integers is a positive integer.Procedure: To add a positive and a negative integer (or a negative and a positive integer), follow these steps:1. Find the absolute value of each integer.2. Subtract the smaller number from the larger number you get in Step 1.3. The result from Step 2 takes the sign of the integer with the greater absolute value.


if the signs are the same you must add its opposite.

The answer is -10. Subtracting a positive integer from a negative integer increases the negative value. Example : If you owed someone 7 dollars and lost 3 more to them, you would be in debt for 10.


When subtracting negative integers, one can relate it to the overall attitude of a room. If a room contains a number of people of positive and negative attitude you can get rid of people (or subtract people) with negative attitudes to make the overall attitude of the room more positive. If you subtract a negative integer it makes it positive.
