1.1 Part 1: Adding & Subtracting Integers

How can you simplify algebraic expressions using the properties of integers?

Multiple Choice

What's a way to define absolute value?

• The value of a number

• The opposite of a number

• The distance of a number from zero

• The multiplicative inverse of a number

Multiple Choice

Is absolute value always positive?

• yes

• no

Multiple Choice

What is the reason that absolute value is always written as a positive?

• Absolute value is talking about numbers so it must be positive.

• Absolute value does not always have to be positive.

• Absolute value is like a clock it has only positive numbers.

• Absolute value is talking about distance, distance is always measured by positive numbers.

Multiple Choice

Multiple Choice

What is the rule for adding integers with same sign?

• Find the difference of the absolute values and take sign of larger absolute value.

• Subtract and keep the sign.

• Add and take sign of larger number.

• Find the sum of the absolute values and keep the sign.

Multiple Choice

What do you do when you are adding integers with different signs?
