Absolute Value & Order Of Operations Expressions Lesson 1

The distance from zero on a number line Absolute Value – Notes The distance from zero on a number line +3 +3 │ │ What symbol means Absolute Value?

Absolute value – practice 𝟗+𝟖=𝟏𝟕 𝟐𝟖−𝟐𝟔=𝟐 𝟑−𝟏𝟗=−𝟏𝟔 Positive number remain positive, negative numbers become positive! Note that the operational symbol ( + and - ) does not change!

Who is correct? Tessa, I think that 𝟒∗𝟐+𝟓=𝟏𝟑. Hey Meghan, Did you know that 𝟒∗𝟐+𝟓=𝟐𝟖?
