Simple addition and subtraction on a number line is demonstrated. free practice worksheets for this skill at: bit.ly k5 fv8t (addition) and b. A number line is a great way to add and subtract. let's see how our meerkat uses the number line. first up, we'll try adding. let's start with 6 plus 3.
Let's see, in this first number line we're starting at 47, then we add 20 to get to 67. and then we add two to get to 69. so if you add 20, and then you're adding two, you're adding 22. so this one seems right. so let's see why these choices don't seem right. so this one, we add two to get to 49 and then two more to get to 51. To start, locate the first number which is −1. then, add 6 to it which means moving the existing point, 6 units to the left of the number line. ii. steps on how to subtract numbers by converting to addition on the number line. the process of subtracting numbers is very similar to adding numbers but with a very slight “twist”. Number line. (the line continues left and right forever.) a number on the left is less than a number on the right. a number on the right is greater than a number on the left. try this interactive number line (click to mark): you can also try the zoomable number line. place these people on the number line to find who is poorest and who is richest. We can use the number line to help us add: 5 3 = 8. and subtract: 6 − 5 = 1. it is also great to help us with negative numbers: −3 2 = −1. −3 − 2 = −5. so when we get puzzling questions like "what is −6 plus 3" we can use the number line!.
