Simplify with Vectors

Lesson Page 4, Section 2

What you'll work on

Substitute the values u⃗ = ⟨2⟩ and v⃗ = ⟨4⟩ into vector expressions and use integer rules to compute the result.

Big Idea for this lesson

$A horizontal painted number line with evenly spaced tick marks, two amber arrows of different lengths hovering above the line — one shorter arrow and one longer arrow, both pointing toward different specific tick positions, the two arrows visually paired and suggesting addition. Painterly soft edges, ivory background, no text or numbers.$

Replace each variable with its value, then apply integer rules. Positive numbers point forward; negative numbers point backward. The math works just like integer addition.
