Which choice below?

$658-$218+$145

$658-$218+145

Answer 1

$658-218-145

I know its not on the equations lists, but I just wanted to give an answer just in case. Rib just loses money. He spent 218, and gave his brother 145.

Answer 2

$658-$218-$145

Explanation:

So I didn't see this equation in your list, but this is the correct way of expressing it. Both of these are expenses in which Rib spent/gave money, so both values are negative
