Use pictures or words to explain how you can solve 7-3 by counting back

You know that in a number line the numbers go like this

1, 2, 3, 4, 5, 6, 7, 8, 9, 10, and so on.

If you take 7 and take away 3 it means you don't have 3 any more.

Think of it like this...

I have 7 cubes. I lost 3 cubes. How many cubes do I have now?

Well you know that 3 backward from 7 is 4, so 7-3 is 4.

i don't have the answer rn but go to math papa. it shows the steps and the answer. hope this : )

step-by-step explanation:

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
