Absolute Value Equations, Subtracting Integers

The distance a number is from zero on a number line is defined as:

• integer

• negative

• operation

• absolute value

What is the absolute value of |-99|.

• 99

• -99

• 0

• It doesn't have one

− | -13 | =

• 0

• 13

• undefined

• − 13

Keep the sign of your first number. Change the subtraction sign to addition. Change the sign of your second number to its opposite/additive inverse. Then apply the rules for addition with same signs OR different signs.

• Adding Integers Rule 

• Subtracting Integers Rule 

• Multiplying Integers Rule 

• Dividing Integers Rule 

What is the rule for subtracting integers?

• Rewrite as addition and follow the addition rules

• Just use the addition rules

• Add and keep the sign

• Subtract and keep the sign of the higher number.

What can I do to the hanger to get the x by itself and keep the hanger balanced?

• add 3 to both sides

• subtract 8 from both sides

• add 8 to both sides

• subtract 3 from both sides

What is the distance between -8 and its opposite?

• 8

• -8

• 16

• -16

5 - (-12)

• -7

• 7

• 17

• -17

What is the rule for subtracting integers?

• Keep the first number the same and add the second number

• Keep the first number the same and add the opposite of the second number

• Keep the first number the same and subtract the opposite of the second number

• Subtracting will always result in a negative answer

Subtracting an integer is the same thing as adding ___.

• its additive inverse

• its absolute value

• the fraction

• the integer
