Write the subtraction problem as an equivalent addition problem. Explain. 46 - 15
46+ (-15)
I understood that as the answer...I just don't know how to explain the reasoning. That is where I always have trouble and the reasoning is worth the most points. Thank you!
To write the subtraction problem 46 - 15 as an equivalent addition problem, we can use the concept of the inverse operation. The inverse operation of subtraction is addition, which means that we can find an equivalent addition problem by using the inverse of the number being subtracted.
To convert 46 - 15 into an equivalent addition problem, we need to add the inverse of 15. The inverse of 15 is -15. Therefore, we can write the subtraction problem as 46 + (-15).
In this form, we are essentially adding the value of -15 to 46.
