Write or draw to explain two ways you can find the sum of 3+4+5

Here, the given problem,

3+4+5,

By the associative property,

3+4+5 = 3 + (4 + 5) = (3+4) + 5

First way :

(3+4) + 5

In the number line,

Start from 3, go right side 4 unit resultant number is 7,

Then again go right side 5 units the resultant number is 12.

That is, (3+4) + 5 = 12

Second way :

3 + (4 + 5),

Start from 4, go right side 5 units, the resultant number is 9,

Then, start from 3 go right side 9 units, the resultant number is 12.

That is, 3 + (4 + 5) = 12

the correct answer to your question is a. 4^4

good luck my friend!

hope this !

maybe if i you could me by giving me brainliest?
