Multiplying Integers

Question 5 • Pre-Algebra - MA3119 A ? Distance Learning

Using the integer tiles interactive, what steps do you need to do to evaluate the following expression? Select two options. –5(–2)

Answer
A
Drag 5 sets of –2 tiles to the window.
B
Drag zero pairs to the window.
C
Remove the 5 groups of –2 tiles.
D
Remove 5 negative tiles from the window.

Explanation

To model –5(–2), use the negative 5 to mean remove 5 groups, with 2 negative tiles in each group. Since the window starts without enough negative tiles to remove, first drag in zero pairs; then remove the 5 groups of –2 tiles. Removing 10 negative tiles leaves 10 positive tiles, so the product is +10.
