How do you use absolute value to add integers?

To add two integers using the absolute value strategy first look at the signs of the two integers.

  1. If the two integers have the same sign: Add their absolute values.
  2. If the two integers have different signs: Subtract the lesser absolute value from the greater absolute value.

Considering this, what are the rules for absolute value?

When we take the absolute value of a number, we always end up with a positive number (or zero). Whether the input was positive or negative (or zero), the output is always positive (or zero). For instance, | 3 | = 3, and | –3 | = 3 also.

Likewise, how can you use absolute value to tell whether the sum of two integers is positive or negative? To find the sum of a positive and a negative integer, take the absolute value of each integer and then subtract these values. The result takes the sign of the integer with the larger absolute value. The sum of any integer and its opposite is equal to zero.

Then, how can you use what you know about adding integers to add rational numbers?

Just remember these tips.

  1. Line up the decimals when you add or subtract.
  2. Don’t forget about the numbers you borrow or carry over.
  3. Translate word problems into equations.
  4. Adding a positive integer with a negative integer is just like subtraction.
  5. Adding two negative integers will give you a negative sum.

What is the absolute value of a negative number?

Absolute Value. Absolute value describes the distance of a number on the number line from 0 without considering which direction from zero the number lies. The absolute value of a number is never negative.

How do you explain absolute value?

Absolute Value. Absolute value describes the distance of a number on the number line from 0 without considering which direction from zero the number lies. The absolute value of a number is never negative.

How do you do absolute value in algebra?

Absolute value equations are equations where the variable is within an absolute value operator, like |x-5|=9. The challenge is that the absolute value of a number depends on the number’s sign: if it’s positive, it’s equal to the number: |9|=9. If the number is negative, then the absolute value is its opposite: |-9|=9.
