Hi there!
equation:521+479=1000..
<em><u>If your subtract 479 from 1,000, in addition form it should be the opposite..</u></em>
we also know that adding’s oppsite is subtracting and multiplyin’s opposite is dividing..
Therefore, the equation Erin used to check his answer would be 521+479=1,000..
3*5=15 15*200=3000centimeters.
Hope this helps!
