Instructions and help about 1 Title Ordering, Adding, And Subtracting Integers Brief Overview

in this video we're going to focus on adding and subtracting integers but in the first half we're just going to focus on adding integers let's start with something simple what is 3 plus 5 intuitively you know what the answer is but let's say if you didn't know what to do here's what you can do you can use a number line to help you add and subtract numbers so let's say this is 0 and we're going to start with 3 so start with the first number anytime you need to add travel on the right using the number line if you need to subtract then move towards the left so we wish to add 5 to 3 so we have to travel 5 spaces to the right 1 2 3 4 5 this is 4 5 6 7 8 that's where we ended up so three plus five is eight let's work on another example 4 plus 3 so if we start with 4 and if we travel three spaces to the right this is going to be 5 6 7 so therefore 4 plus 3 is equal to 7 and so using a number line is very helpful you will never need to add or subtract two integers is another example what is 8
