A number line has arrows because the numbers keep going forever. You can use the number line to practice the addition and subtraction. Method: Draw a number line with numbers. To find difference, we first go forward till we reach the bigger number and then backward till we reach the smaller number. To find sum, we first go till the first number and then move further from there to reach the next number. Directions: Answer the following questions. 1) Draw a number line and show zero, positive numbers and negative numbers. 2) Also write at least ten examples with subtraction and addition using number line.
