## What are positive and negative numbers?

About Positive and Negative Numbers Positive numbers are any numbers greater than zero, for example: 1, 2.9, 3.14159, 40000, and 0.0005.

For each positive number, there is a negative number that is its opposite.

…

Negative numbers are less than zero (see the number line for a more complete explanation of this)..

## Why when you subtract a negative is positive?

So, subtracting a positive number is like adding a negative; you move to the left on the number line. Subtracting a negative number is like adding a positive; you move to the right on the number line.

## Do 2 positives make a positive?

Once you have the numerical answer, then you can apply a very simple rule to determine the sign of the answer: When the signs of the two numbers are the same, the answer will be positive. When the signs of the two numbers are different, the answer will be negative.

## What is a positive times a positive?

Rule 1: A positive number times a positive number equals a positive number. This is the multiplication you have been doing all along, positive numbers times positive numbers equal positive numbers. For example, 5 x 3 = 15. 5 is a positive number, 3 is a positive number and multiplying equals a positive number: 15.

## What does a positive and a positive make?

Two ‘pluses’ make a plus, two ‘minuses’ make a plus. A plus and a minus make a minus. If two positive numbers are multiplied together or divided, the answer is positive.

## What is the rule for adding and subtracting positive and negative numbers?

The Rules:RuleExample+(+)Two like signs become a positive sign3+(+2) = 3 + 2 = 5−(−)6−(−3) = 6 + 3 = 9+(−)Two unlike signs become a negative sign7+(−2) = 7 − 2 = 5−(+)8−(+2) = 8 − 2 = 62 more rows

## How do you add positive and negative numbers?

Rule 3: Adding negative numbers to positive numbers—count backwards, as if you were subtracting. Now, let’s look at the reverse equation. When you are adding a negative number to a positive number you are effectively subtracting the second number from the first. For example, take 4 + (-2).

## Why do 2 negatives make a positive?

Each number has an “additive inverse” associated to it (a sort of “opposite” number), which when added to the original number gives zero. … 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.

## What are the four rules of maths?

The four basic mathematical operations–addition, subtraction, multiplication, and division–have application even in the most advanced mathematical theories. Thus, mastering them is one of the keys to progressing in an understanding of math and, specifically, of algebra.

## What is the rule for subtracting negative numbers?

Rule 3: Subtracting a negative number from a negative number – a minus sign followed by a negative sign, turns the two signs into a plus sign. So, instead of subtracting a negative, you are adding a positive. Basically, – (-4) becomes +4, and then you add the numbers. For example, say we have the problem -2 – –4.

## What are the three rules for adding and subtracting integers?

To add integers having the same sign, keep the same sign and add the absolute value of each number. To add integers with different signs, keep the sign of the number with the largest absolute value and subtract the smallest absolute value from the largest. Subtract an integer by adding its opposite.

## What is the quotient of two negative numbers?

When you divide a negative number by a positive number then the quotient is negative. When you divide a positive number by a negative number then the quotient is also negative. When you divide two negative numbers then the quotient is positive.
