Integer Practice

Introduction of integer practice:

We know that integers have positive and negative numbers. Each negative numbers is matching with a positive number the similar distance from 0 on a number line. Example: -6,-5,-4,-3,-2,-1,0,+1,+2,+3,+4,+5,+6. We can write them down like this: {…,-3,-2,-1, 0,1,2,3}. Here we are going to learn how to practice integers.

Rules:

Rules for adding integers:

Rule 1:  Suppose if add the same sign, add the two numbers and put their common sign.

(+62) + (+14) = +76 (-29) + (-13) = -42.

Rule 2:  Suppose if we add the different signs, we need to find the difference between the two numbers and put the sign of the number.

(+15) + (-8) = +7 (+9) + (-30) = -21

Rules for subtracting integers:

Rule 1: Commonly every subtraction problem can be rewrite as a corresponding addition problem,

Use the follow rule: To subtract an integer, add its reverse.

1. (-8) – (+9) = The opposite of +9 is –9. Change sign to opposite: (-8) + (-9) = -17 using Integer addition rules

Switch rule 1 to subtract signed numbers:

Step 1: First, change double negatives to a positive.

Step 2: Get a sum of terms with same signs and keep the given sign, using the sign in front of the number as the sign of the number.

Step 3: Get the difference when the terms have different signs and use the sign of the larger numeral. Understanding Radian Measure is always challenging for me but thanks to all math help websites to help me out.

Practice Problems for Integers:

Practice adding positive integers:

We know that addition is the basic operations in math. Here we are going see some practice problems of addition.

Example 1:

23+21.

Solution:

Here both the numbers are positive .And then addition process is done here.

The result  is 23+21 = 44.

Practice adding negative integers:

-256 +-24.

Solution:

When we take this above problem, we have both negative numbers. And we need to find the total of these two numbers. And negative 256 plus negative 24 equals negative 280.

The result is -280.

Practice subtraction integers:

Turn the subtraction symbol into addition and get the reverse of the second number. Then take the problem as an addition problem.

Example 1:

Integer subtraction:

-128+18.

Solution:

Here the first number is negative and the next number is positive. The subtraction procedure is finished. The biggest number sign will appear to answer

The result is -128+18= 110.
