The rules for subtracting integers are given below: If we subtract 0 from any integer, the answer will be the integer itself. If we subtract any integer from 0, we will find the additive inverse or the opposite of the integer. Subtraction of integers is done by changing the sign of the subtrahend.
Subtracting integers is the method of finding the difference between two integers having the same or different signs. Subtraction of integers can be written as the addition of the first number and the additive inverse of the second number.
Learn how to subtract Integers. See the rules for adding and subtracting integers, the method to perform the subtraction, and see related examples.
Steps on How to Subtract Integers. Step 1: Transform the subtraction of integers problem into addition of integers problem. Here’s how: First, keep the first number (known as the minuend). Second, change the operation from subtraction to addition. Third, get the opposite sign of the second number (known as the subtrahend)
Subtracting Integers. Subtracting integers is easy when you use the keep change change rule. This rule allows you to rewrite the subtraction problem as an addition problem and then follow the addition rules.
Using “Adding Two Integers with Unlike Signs” from Section 2.2, first subtract the smaller magnitude from the larger magnitude; that is, 117 − 115 = 2. Because −117 has the larger magnitude and its sign is negative, prefix a negative sign to the difference in magnitudes.
Doing the Manipulative Mathematics activity "Subtraction of Signed Numbers" will help you develop a better understanding of subtracting integers. We will model four subtraction facts using the numbers 5 5 and 3 . 3 .
