| −(−) | 6−(−3) = 6 + 3 = 9 | |
| +(−) | Two unlike signs become a negative sign | 7+(−2) = 7 − 2 = 5 |
| −(+) | 8−(+2) = 8 − 2 = 6 |
How do you add a positive and negative number?
To get the sum of a negative and a positive number, use the sign of the larger number and subtract. For example: (–7) + 4 = –3. 6 + (–9) = –3.
Why is minus minus a plus?
The fact that the product of two negatives is a positive is therefore related to the fact that the inverse of the inverse of a positive number is that positive number back again.
How do negatives work?
To get a negative number, you need one negative and one positive number. The rule works the same way when you have more than two numbers to multiply or divide. An even number of negative numbers will give a positive answer. An odd number of negative numbers will give a negative answer.
What is an A minus grade?
While professors control where each plus or minus cut off begins, a typical grading scale, the one I will use throughout this article, follows this pattern: A = 100-93, A- = 92.9-90, B+ = 89.9-87, B = 86.9-83 and so on.
What is an A minus GPA?
The 4.0 GPA Scale A 4.0 represents an A or A+, with each full grade being a full point lower: 3.0=B, 2.0=C, and 1.0=D. Pluses are an additional one-third of a point, while minuses are the subtraction of one-third of a point. For example, an A- is a 3.7, and a B+ is a 3.3.
Do I add or subtract first?

What is the difference between Plus and minus in math?
That is, by plus-ing a minus, you’re adding in the other direction. In the same vein, if you subtract a negative (that is, if you minus a minus), you’re subtracting in the other direction; that is, you’ll be subtracting by moving to the right.
How do you subtract 5 from 9 using a minus sign?
The easiest way of dealing with this is to do the subtraction “normally” (with the smaller number being subtracted from the larger number), and then put a “minus” sign on the answer: 9 – 5 = 4, so 5 – 9 = –4.
What is the value of positive 6 Plus negative 3?
“Positive 6 plus Negative 3 equals Positive 3” We could write it as (+6) + (−3) = (+3) 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:
What does a ± sign mean in math?
In other words, when you see a ± sign, you need to understand that it doesn’t mean that “the equation holds whether we put a minus or a plus sign in there”, but think of it more as like “the variable on the left-hand side can take on the values of the right-hand side, whether the ± is actually a + or a −.
