Among the most universally recognized symbols in mathematics is the − symbol, representing the "Minus Sign". This simple yet profound symbol finds application across a spectrum of mathematical operations and contexts.
The plus sign (+) and the minus sign (−) are mathematical symbols used to denote positive and negative functions, respectively. In addition, + represents the operation of addition , which results in a sum , while − represents subtraction , resulting in a difference . [ 1 ]

Mar 12, 2024 · The minus symbol (-) signifies subtraction. When you're subtracting one number from another, place the minus sign between them. For instance, 6 - 3 shows that you're subtracting 3 from 6. As with the plus symbol, you can place the minus symbol in front of a number to show that it has a negative value.

On the Number Line positive goes to the right and negative to the left. Try the sliders below and see what happens:
Let us think about numbers as balloons (positive) and weights (negative): This basket has balloons and weights tied to it:
Adding positive numbers is just simple addition. We can add balloons (we are adding positivevalue) the basket gets pulled upwards (positive)
Subtracting positive numbers is just simple subtraction. We can take away balloons (we are subtracting positivevalue) the basket gets pulled downwards (negative)
Now let's see what adding and subtracting negativenumbers looks like: We can add weights (we are adding negativevalues) the basket gets pulled downwards (negative) The last two examples showed us that taking away balloons (subtracting a positive) or adding weights (adding a negative) both make the basket go down. So these have the same result: 1. (...
Lastly, we can take away weights (we are subtracting negativevalues) the basket gets pulled upwards (positive) Yes indeed! Subtracting a Negative is the same as adding! Two Negatives make a Positive
It can all be put into two rules: They are "like signs" when they are like each other (in other words: the same). So, all you have to remember is:
And there is a "common sense" explanation: So, two negatives make a positive, and if that satisfies you, then you are done!
Ally's Points
Ally can be naughty or nice. So Ally's parents have said "If you are nice we will add 3 points (+3). If you are naughty, we take away 3 points (−3). When you reach 30 Points you get a toy." So when we subtract a negative, we gain points (i.e. the same as adding points). See: both "15 − (+3)" and "15 + (−3)" result in 12. So: It doesn't matter if you subtract positive points or add negative points, you still end up losing points.
The minus symbol (−) is a mathematical symbol used primarily to denote the operation of subtraction and to indicate negative values. In mathematics, it serves as a critical tool for expressing the removal of one quantity from another, as in equations such as (5 – 2 = 3).
The meaning of MINUS SIGN is a sign — used in mathematics to indicate subtraction (as in 8—6=2) or a negative quantity (as in —10°) —called also negative sign.
