Show one way to count from $82 to $512 without subtraction or multiplication, but on a number line? this is me tryin to understand my second graders math homework and i am feeling horribly stupid about it. any answers to this specific question?

Okay, so we start at '$82'

$82

let's add $100

$82+$100=$182

lets add another 100

$82+$100+$100=$282

lets add another $100

$82+$100+$100+$100=382

lets add another $100

$82+$100+$100+$100+$100=$482

Now we can't add another $100, since that will take us to $582, and we need to get to $512, so lets add $20

$82+$100+$100+$100+$100+$20=$502

Okay, we're getting really close! Let's add $10.

$82+$100+$100+$100+$100+$20+$10=$512

(If you were to show your work on a number line, you would simply keep moving up by $100 until you couldn't anymore, and then move up by $20, and finally by $10, until we get to $512)

a simpler way to solve this...

Okay, so we start at '$82'

$82

let's add $400

$82+$400=$482

now lets add $30

$82+$400+$30=$512

**Hope this helps

Bc equals mb that should be your answer
