Step-by-step explanation:
The number line is just a line with numbers marked off at regular intervals. You probably saw your first number line when you were learning how to count to ten. You can use this trusty tool to perform the Big Four operations (adding, subtracting, multiplying, and dividing) on relatively small numbers.
The number line can be a useful tool for adding and subtracting small numbers:
When you add, move up the number line, to the right.
When you subtract, move down the number line, to the left.
To multiply on the number line, start at 0 and count by the first number in the problem as many times as indicated by the second number.
To divide on the number line, first block off a segment of the number line from 0 to the first number in the problem. Then divide this segment evenly into the number of pieces indicated by the second number. The length of each piece is the answer to the division
