Meaning of Subtraction
Subtraction means taking away a smaller number from a larger number to find the difference or what is left over, represented by the minus sign (-).
Column Subtraction (Without Borrowing)
Arranging 2-digit numbers in Tens (T) and Ones (O) columns and subtracting the ones digit first, followed by the tens digit.
Properties of Zero in Subtraction
When you subtract zero from any number, the number remains exactly the same. When you subtract a number from itself, the answer is always zero.
Subtraction Word Problems
Reading story sums carefully to identify key phrases like 'left', 'took away', or 'how many more' to set up the correct subtraction sentence.

Frequently Asked Questions
Which digit should I subtract first in a 2-digit number?
Always start subtracting from the Ones column on the right side before moving to the Tens column on the left.
What is the difference between Minuend and Subtrahend?
The minuend is the starting big number, and the subtrahend is the smaller number that you take away from it.
How can I check if my subtraction answer is correct?
You can add your answer (difference) to the smaller number (subtrahend); if it equals the top number (minuend), your answer is right.
