## What is the rule for adding 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 subtract a negative from a negative?

Find out why subtracting a negative number is the same as adding the absolute value of that number. Created by Sal Khan.

## What is a negative times a positive?

Rule 2: A negative number times a positive number equals a negative number. When you multiply a negative number to a positive number, your answer is a negative number. It doesn’t matter which order the positive and negative numbers are in that you are multiplying, the answer is always a negative number.

## Does a minus times a minus equal a positive?

When We Multiply: Yes indeed, two negatives make a positive, and we will explain why, with examples!

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

When adding positive numbers, count to the right. When adding negative numbers, count to the left. When subtracting positive numbers, count to the left. When subtracting negative numbers, count to the right.

## Why is a positive minus a negative positive?

Subtracting a number is the same as adding its opposite. 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.

## Why does a minus and a minus make a plus?

The answer has to do with the fundamental properties of operations on numbers (the notions of “addition”, “subtraction”, “multiplication”, and “division”). … Each number has an “additive inverse” associated to it (a sort of “opposite” number), which when added to the original number gives zero.

## What is negative plus negative?

When you are adding a negative number to a negative number, it becomes subtraction, where you start from a negative point on the numbers line and move left. For example, -3 + (-2). This reads “negative three plus negative 2”. … Then we subtract 2. The answer is -5.

## What is the rule for multiplying and dividing positive and negative numbers?

With two numbers, the rules for multiplying and dividing positive and negative numbers are not only simple, but they’re also the same for both operations: When multiplying or dividing two numbers, if the two signs are the same, the result is positive, and if the two signs are different, the result is negative.

## What is the rule for adding and subtracting integers?

When a positive and a negative integer are added, the numbers are subtracted without signs and the answer is assigned the sign of the larger integer. For example, to add 10 + (-15) = -5, the larger number in this case is 15 without the sign.

## What happens when you subtract a negative from a positive?

Rule 4: Subtracting a negative number from a positive number—when you see the subtraction (minus) sign followed by a negative sign, turn the two signs into a plus sign. Thus, instead of subtracting a negative, you’re adding a positive, so you have a simple addition problem.

## What is the rule for adding subtracting multiplying and dividing?

Over time, mathematicians have developed a set of rules called the order of operations to determine which operation to do first. The rules are: Multiply and divide from left to right. Add and subtract from left to right.

## Does a negative plus a negative make a positive?

When you have two negative signs, one turns over, and they add together to make a positive. If you have a positive and a negative, there is one dash left over, and the answer is negative.

## What does a positive plus a negative equal?

Multiplication and Division If two positive numbers are multiplied together or divided, the answer is positive. If two negative numbers are multiplied together or divided, the answer is positive. If a positive and a negative number are multiplied or divided, the answer is negative.

## What happens when you subtract a negative from a negative?

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.

## What is the quotient of two negative numbers?

RULE 3: The quotient of two negative integers is positive.

## Can two positives make a negative?

Being Rh-positive or Rh-negative means that either you have the Rhesus D antigen on your RBCs (positive) or you don’t (negative). … So, is it possible for two people who are Rh-positive to produce a child that’s Rh-negative? The answer is yes — but only if neither parent passes along Rhesus D.
