The minus sign (−) represents subtraction: finding how many remain after taking away, comparing two quantities to find the difference, or determining an unknown part in a related addition fact. A learner interprets and writes subtraction equations such as 9 − 4 = 5, understanding that the sign relates quantities and their result rather than indicating that the following number is negative; work is limited to whole numbers within 20, not negative numbers or formal algebraic generalizations.
The minus sign, , means take away or find how many are left.
Example: You have apples and take away .
Write the subtraction equation:
Read it as: “Eight minus three equals five.” The minus sign tells us to take away from .
