Exercises: Operations on Integers
Work through each section in order. Use a number line to check your add/subtract answers.
Recall / Warm-Up
On a number line, which side of zero are the negative numbers?
The right side
The left side
What is the opposite of +5?
Add 8 + 6 (whole numbers).
Fluency Practice
Order the integers -4, 3, 0, -1, 2 from smallest to largest: ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ , ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ , ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ , ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ , ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ .
Which is larger, −6 or −2?
−6, because 6 is a bigger digit than 2
−2, because it sits further right on the number line, even though 2 is a smaller digit than 6
They are equal.
Compute −3 + 5 (start at −3, step 5 right).
Compute 4 − 6 (start at 4, step 6 left).
Compute (+3) × (−4) by repeated addition of −4, three times.
Compute (−5) × (−4).
