Why do you add when you subtract negative numbers?

The addition/subtraction tells us which way to face, and the positive/negative tells us if our steps will be forward or backward (regardless of the way we’re facing).

What is the rule for adding positive and negative numbers?

Do you add or subtract two 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.

When the signs are the same you add?

Same Sign – Add the absolute values and give the answer the same sign. Subtracting Integers – Same as adding the opposite of that integer number.

How do you add two negative numbers?

Note: Adding two negative numbers together? Just add the absolute value of each number together, put a negative sign in front, and you have your answer!

What is the rule for subtracting two negative numbers?

Subtracting a number is the same as adding the opposite of the number. Note: In both examples, we change subtraction to addition and changed the sign of the second number to the opposite sign.

When 2 negative integers are added we get?

Summary: Adding two positive integers always yields a positive sum; adding two negative integers always yields a negative sum. To find the sum of a positive and a negative integer, take the absolute value of each integer and then subtract these values.

What is a positive minus a negative?

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.

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.
