Subtracting integers is the method of finding the difference between two integers. These two integers may have the same sign or different signs. The set of integers is represented by Z= {โฆ,-3,-2,-1,0,1,2,3,โฆ}. If we subtract the integer b from the integer a, we write it as a - b. Example: Subtract 7 from 9. 9 - 7 = 2

When we get to the integers, there are some pretty concrete rules to follow for multiplication and division. But this isn't so true for addition and subtraction. This trips kids when working on integer operation problems, solving equations, finding inverses and any other time numbers on either side of zero need to be combined.

Steps for Subtracting Integers. To subtract two integers on a number line, we follow the following steps: Step 1: Draw a line and choose an arbitrary point as 0, with negative numbers to the left of 0 and positive numbers to the right of 0. Step 2: Start from 0 and move as many points as the first number to the.

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) Finally, proceed with the regular addition of integers. Step 2: Proceed with the regular addition of the integers. Note that you will eventually add integers.

Subtraction Using Integers Rules Chart. Following are the rules for subtracting integers: When we subtract 0 from any integer, the result is the integer itself. We may discover the additive inverse or opposite of any integer by subtracting it from 0. Integer subtraction is accomplished by changing the sign of the subtrahend.

Addition and Subtraction ( +, โ) Visualize adding 3 + 2 on the number line by moving from zero three units to the right then another two units to the right, as illustrated below: Figure 1.2.1. The illustration shows that 3 + 2 = 5. Similarly, visualize adding two negative numbers ( โ 3) + ( โ 2) by first moving from the origin three units.

In each case, subtraction means "add the opposite." a) Change the subtraction to addition with the phrase "subtraction means add the opposite." That is, 4โ8 = 4+(โ8). We can now perform this addition on the number line. Thus, 4 โ 8=4+(โ8) = โ4. b) First change the subtraction into addition by "adding the opposite."
