## Subtraction of Larger Number from Small Number:

The subtraction of a larger number from a smaller number is the process of determining the difference between the two numbers. In mathematical terms, this process is known as subtraction. The subtraction of a larger number from a smaller number can be accomplished using a number line.

To subtract a larger number from a smaller number, first line the numbers up on a number line. The larger number should be on the right, and the smaller number should be on the left. Then, subtract the numbers by moving from the right to the left. The difference between the two numbers is the result of the subtraction.

For example, if you want to subtract 5 from 2, you would line up the numbers on a number line. The 5 would be on the right, and the 2 would be on the left. Then, you would subtract the numbers by moving from the right to the left. The difference between the two numbers is 3.
