Using the number line, add 3 and 5.
This means 3 + 5
Start at 0, move 3 steps forward. We land on 3.
Now, from 3, move 5 steps forward.
We land on 8.
Hence 3 + 5 = 8
Use number line and add the following integers:
(–1) + (–2) + (–3)
Question 2 (b)
5 + (–11)
Question 3 (a)
Add without using number line: 11 + (–7)
Question 3 (d)
Add without using number line: (–250) + (+150)
Question 3 (f)
Add without using number line: (–217) + (–100)
