• Subtraction is one of the four basic operations in mathematics.
• The subtraction sign is the minus symbol (–), which is read as 'minus'.
• Subtraction is the inverse operation of addition, undoing what addition performs.
• Subtraction means to take away, reduce, remove, or count backward to make a number smaller.
• The result of a subtraction problem is called the difference.
• In subtraction, the larger number is called the minuend and the smaller number subtracted is the subtrahend.
• The formula for subtraction is: Minuend – Subtrahend = Difference.
• Any number minus 0 equals the number itself (e.g., 5 – 0 = 5).
• Any number minus 1 equals its predecessor or the number immediately before it (e.g., 8 – 1 = 7).
• Any number minus the same number equals 0 (e.g., 9 – 9 = 0).
• To subtract, you always start from the rightmost digit (the ones place) and move left to the tens and hundreds places.
• When subtracting larger numbers, you can use strategies like counting up on a number line or decomposing numbers into place values.
