A number line is a horizontal line with segments and numbers marked on it.
To use a number line for addition, start at the first number on the number line and then move to the right by the same amount as the second number.
For example, to solve 2 + 1. Start at the number 2 then move to the right by 1 to get the answer, 3.
To use a number line for subtraction, start at the first number on the number line and then move to the left by the same mount as the second number.
For example, to solve 5 - 2. Star at the number 5 then move to the left by 2 to get the answer, 3.
