How do you write negative numbers on a calculator?
You know now that the answer will be negative, because you're subtracting a bigger number than you'd started with (the nine is bigger than the five). 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 rule when adding negative numbers?
What is a negative number?
Negative numbers are our numbers less than zero. On the number line, they are all to the left of the 0. They match the positive numbers to the right of 0. All negative numbers have a minus or negative sign in front of them. If we ignore the negative sign, a really small negative number will seem to be really large.
What does an ordered list of negative numbers look like?
In reality, they are getting smaller and smaller. Because of this, an ordered list of negative numbers will look like it is written backwards. Just remember that with negative numbers, the larger the number after the negative sign, the smaller it is. Learning Outcomes.
How do you deal with adding and subtracting negatives?
How do you deal with adding and subtracting negatives? The process works similarly to adding and subtracting positive numbers. When you'd added a positive number, you'd moved to the right on the number line. When you'd subtracted a positive number, you'd moved to the left.
What happens when you subtract a negative?
If you remove a hot cube (subtract a positive number), the temperature goes down. And if you remove a cold cube (subtract a negative number), the temperature goes UP! That is, subtracting a negative is the same as adding a positive. Now suppose you have some double cubes and some triple cubes.
Is subtracting a negative the same as adding a positive?
That is, subtracting a negative is the same as adding a positive. Now suppose you have some double cubes and some triple cubes. If you add three double-hot cubes (add three-times-positive-two), the temperature goes up by six. And if you remove two triple-cold cubes (subtract two-times-negative-three), you get the same result.
No Sign Means Positive
If a number has no sign it usually means that it is a positive number.

What is negative number?
Negative numbers have a value of less than zero. These numbers are found when working with the numbers on the left side of the number line. Negative numbers can be added, subtracted, multiplied, and divided just like positive numbers. However, special rules apply when carrying out operations with negative numbers.
Can you multiply negative numbers?
Therefore, you can count the number of negative signs when you have a list of numbers to multiply. The answer will be positive if you have an even number of negative signs. The answer will be negative if you have an odd number of negative signs.

Addition of Negative Numbers
- Case 1:When a negative number is added to a negative number, we add the numbers and use the negative sign in the answer. For example, -7 + (- 4) = -7 - 4 = -11. In other words, the sum of two negative numbers always results in a negative number. This can be understood with the help of a number line. The number line rule says, "To add a negative number we move to the left on the nu…
Subtraction of Negative Numbers
- The subtraction of negative numbers is similar to addition. We just need to remember a rule which says: Rule of Subtraction: Change the operation from subtraction to addition, and change the sign of the second number that follows. Case 1: When we need to subtract a positive number from a positive number, we follow the subtraction rule given above. For example, 5 - (+6) becomes 5 + …
