Question

b) Subtract 7 from 5 using a number line​

Answer 1

Simplify by adding the numbers, 3 + (–5).

Locate the first point, 3, on the number line.

Now, we are going to add negative five (-5) which tells us to move the point 5 units going to the left.

We arrive at −2. That’s why 3 + (–5)=–2.
